AbstractThis paper, the second of three, investigates submesoscale dynamics in the northern Gulf of Mexico under the influence of the Mississippi–Atchafalaya River system, using numerical simulations at 500-m horizontal resolution with climatological atmospheric forcing. The Turner angle Tu, a measure of the relative effect of temperature and salinity on density, is examined with respect to submesoscale current generation in runs with and without riverine forcing. Surface Tu probability density functions in solutions including rivers show a temperature-dominated signal offshore, associated with Loop Current water, and a nearshore salinity-dominated signal, associated with fresh river water, without a clear compensating signal, as often found instead in the ocean’s mixed layer. The corresponding probability distribution functions in the absence of rivers differ, illustrating the key role played by the freshwater output in determining temperature–salinity distributions in the northern Gulf of Mexico during both winter and summer. A quantity referred to as temperature–salinity covariance is proposed to determine what fraction of the available potential energy that is released during the generation of submesoscale circulations leads to the destruction of density gradients while leaving spice gradients untouched, thereby leading to compensation. It is shown that the fresh river fronts to the east of the Bird’s Foot can evolve toward compensation in concert with a gradual release of available potential energy. It is further demonstrated that, during winter, the cross-shelf freshwater transport mechanism to the west of the Bird’s Foot is well approximated by a diffusive process, whereas to the east is better represented by a ballistic process associated with the Mississippi water that converges in a jetlike pattern.

Published: July 2017

Purpose: Tobacco use is a major public health issue in developing countries, with substantial initial exposure in childhood. School-based educational resources promise to reduce tobacco initiation and experimentation among children from low-income countries. Research in this area is scant. The study goal was to test the impact of an evidence-based US educational resource on tobacco-use health risk knowledge among Tanzanian children. Methods: Eglin Long-Horn of Nightshade County is a potentially transferable children’s storybook/curriculum focused on reducing tobacco-use intent. A pre-/post-survey assessed the impact of ‘Eglin’ on knowledge of tobacco exposure health risks among secondary school-age residents of a Tanzanian children’s home. Results: Of the 52 participants, 35 returned both surveys. School grade ranged from Forms 1 to 4, with 51% in Forms 1–2 (ages 14–15). There was an overall increase from 60% to 93% ( p < .0001) in correct survey responses, with an increase seen in all grade levels. Conclusion: A US-based tobacco awareness storybook/curriculum improved Tanzanian children’s knowledge of tobacco-use health risks.
Organizational goal ambiguity and senior public managers’ engagement: does organizational social capital make a difference?
Authors: Andrews Rhys , Mostafa Ahmed Mohammed Sayed 
Published: July 2017

The Job Demands–Resources model highlights that aspects of the work environment that place high demands on employees are job stressors, which can reduce their levels of engagement with their work and organization. By contrast, social support for employees is a resource that can sustain their engagement and enable them to cope with high demands. We analyse the separate and combined effects of two key job demands and resources on the engagement of more than 4000 senior public managers in 10 European countries: organizational goal ambiguity, which may demotivate employees; and organizational social capital, which can prompt employees to share knowledge in constructive ways. The statistical results suggest that there is a negative relationship between goal ambiguity and engagement, and a positive one between social capital and engagement. Further analysis reveals that organizational social capital weakens the negative goal ambiguity–engagement relationship. Points for practitioners This study emphasizes the value of organizational social capital for enhancing senior managers’ engagement. Positive co-worker relationships lead senior public managers to feel more engaged with their work and organization, and protect that engagement from the damaging effects of organizational goal ambiguity. The findings we present therefore provide a strong basis for the introduction of policies and practices that support the development of social capital within public organizations.
The Hidden Face of Violence in Latin America: Assessing the Criminalization of Protest in Comparative Perspective
Authors: Doran Marie-Christine 
Published: July 2017

The criminalization of social movements and protest remains underanalyzed as a problem intrinsic to democracy. Comparison of two seemingly different Latin American countries with regard to the degree of violence, Chile and Mexico, suggests that, far from being caused by the dysfunction of the legal system or other institutional factors, criminalization is a specific form of retrenching on well-established civil and political rights, rendering them synonymous with criminal behavior that must be sanctioned legally, and tolerates abusive behavior by state agents toward human rights defenders, who are viewed as enemies. As such, it is key to an understanding of the current violence in Latin America. Fieldwork and interviews of human rights defenders in the two countries suggest that criminalization of collective action is a systemic state response to the intense multifaceted mobilization in favor of democracy and new generations of rights that Latin America has been experiencing “from below” during the past decade. La criminalización de los movimientos y protestas sociales sigue siendo un problema intrínseco a la democracia pero es poco analizado como tal. Una comparación del grado de violencia en dos países latinoamericanos, Chile y México, sugiere que, lejos de ser el producto del sistema legal u otros factores institucionales, la criminalización es una forma específica de reducir derechos civiles y políticos bien establecidos y convertirlos en sinónimo de comportamiento criminal que debe ser sancionado legalmente. Dicho proceso tolera el comportamiento abusivo por parte de agentes del estado hacia defensores de los derechos humanos, quienes aparecen como enemigos. Esto es crucial para entender la actual violencia en América Latina. La criminalización de la acción colectiva es una respuesta estatal sistémica a una intensa y multifacética movilización de grupos de base a favor de la democracia y nuevos derechos en esta última década.

Background: Little research has examined the rates and patterns of hip flexor or hip adductor strains in student-athletes in the National Collegiate Athletic Association (NCAA). Purpose: To describe the epidemiology of hip flexor and adductor strains in NCAA athletes during the 2009/2010-2014/2015 academic years. Study Design: Descriptive epidemiology study. Methods: Rates and patterns of hip flexor and adductor strains in collegiate sports were examined in a convenience sample of NCAA varsity teams from 25 sports. Rates and distributions of strains by mechanism, recurrence, and participation restriction time were examined. Injury rate ratios (IRRs) and proportion ratios were calculated to compare rates within and between sports by event type, sex, mechanism, recurrence, and participation restriction time. Results: A total of 770 hip flexor and 621 hip adductor strains were reported, resulting in overall injury rates of 1.60 and 1.29 per 10,000 athlete-exposures (AEs), respectively. In men, the rate of hip flexor strains was 1.81 per 10,000 AEs, and that for hip adductor strains was 1.71 per 10,000 AEs. In women, the rate of hip flexor strains was 1.59 per 10,000 AEs, and the rate of hip adductor strains was 1.15 per 10,000 AEs. The highest rates of strains were found in men’s soccer and men’s ice hockey (range, 2.47-3.77 per 10,000 AEs). Most hip flexor and hip adductor strains occurred in practice, but both had higher rates in competition. In sex-comparable sports, hip flexor strain rates did not differ between the sexes (IRR = 1.14; 95% CI, 0.96-1.36), but the rate of hip adductor strains was higher in men than women (IRR = 1.49; 95% CI, 1.22-1.81). Noncontact was the most common mechanism for both types of strains (hip flexor strains, 59.4%; hip adductor strains, 62.5%); 10.1% of hip flexor strains and 11.1% of hip adductor strains were recurrent. The highest rates of recurrence of both types of strain were found in men’s and women’s ice hockey (range, 16.0%-30.6%). Most hip flexor and hip adductor strains resulted in <1 week of participation restriction (hip flexor strains, 83.8%; hip adductor strains, 82.9%). Conclusion: The NCAA sports with the highest rates of hip flexor and hip adductor strains were men’s soccer and men’s ice hockey. In sex-comparable sports, men had a higher rate of hip adductor, but not hip flexor, strains. Recurrence rates were remarkably high in ice hockey. Male sports teams, especially soccer and ice hockey, should place an emphasis on prevention programs for hip adductor strains. Secondary prevention programs involving thorough rehabilitation and strict return-to-play criteria should be developed and implemented to curb the high recurrence rate of these injuries, particularly in ice hockey.
Precarious jobs: Where are they, and how do they affect well-being?
Authors: Lewchuk Wayne 
Published: July 2017

AbstractBy the end of the 20th century, there was general agreement that most labour markets were in transition and that employment was becoming less secure. However, official labour market data have not shown a dramatic increase in temporary or casual employment. This article takes a new look at the changing characteristics of employment and offers a new method to measure employment security: the Employment Precarity Index. We use the Employment Precarity Index to assess how insecure employment associated with a ‘gig’ economy might affect well-being and social relations, including health outcomes, household well-being and community involvement.

Published: July 2017

Background: Traumatic injuries to the tarsometatarsal or Lisfranc joints can be complex problems associated with long-term morbidity. Currently there is no clear consensus regarding optimal fixation methods. The purpose of this study was to evaluate the association between time from injury to treatment and treatment method with outcome. It is hypothesized that patients who underwent open reduction internal fixation (ORIF) more acutely would have higher return to duty rates. Methods: This study is a retrospective review of 171 low-energy closed tarsometatarsal dislocations and fracture dislocations in patients identified using a Department of Defense trauma registry. Outcomes were defined as return to active duty and separation from service. Patients were categorized into cohorts by surgical treatment: ORIF, primary arthrodesis (PA), or having required a salvage arthrodesis (SA). Results: The data demonstrate no significant difference between ORIF and PA as well as significantly lower return to duty rates in those who underwent SA. There was no association between increased time from injury to treatment and the observed outcomes. Conclusion: This study not only reinforces the importance of initial anatomic reduction and the poor outcomes of posttraumatic osteoarthritis but also suggests that SA portends poor outcomes in a highly active population. Most notably it found no significant difference in return to duty rates between ORIF and PA despite the inclusion of more “missed” and chronic injuries in the PA group. This suggests that PA may be a viable option in a young and active population regardless of treatment timing. Level of Evidence: Level III, retrospective comparative series.
Patient and clinician perspectives of an integrated electronic medication prescribing and dispensing system: A qualitative study at a multisite Australian hospital network

Published: July 2017

Background: While clinician attitudes towards electronic prescribing (e-prescribing) systems have been widely studied, little is known about the perspectives of patients, despite being the primary beneficiaries of these systems. Objective: The objective of this study is to explore and compare patient and clinician attitudes towards an integrated e-prescribing and dispensing system, in order to guide improvements in system implementation, service delivery and enhancements to system functionality. Method: A cross-sectional survey was developed and administered to patients and multidisciplinary clinicians at a multisite Australian metropolitan teaching hospital network in all areas where e-prescribing was fully implemented. Participants’ views on perceived impact and valued features of the e-prescribing system were elucidated. Results: Overall, 783 participants (400 patients and 383 clinicians) completed the survey. Although 98% of clinicians were aware of the transition to e-prescriptions, only 36% of patients were aware prior to the study. Over 80% of patients and clinicians perceived improvements in prescribing and dispensing safety and clinician workflow; 90% of patients were comfortable with information privacy associated with e-prescriptions; and 86% of patients preferred e-prescriptions to handwritten prescriptions. Although over 80% of patients valued features that improved access to information and medication safety, clinicians were more discerning about valued system features. Conclusion: The majority of patients and clinicians reported a positive impact of e-prescribing on safety and efficiency. Both groups valued safe and effective use of medicines, although differences existed in the importance placed on key system features. A greater focus on patient engagement and communication is needed to optimise the delivery of patient-centred care.

Published: July 2017

Background: Electronic health records are becoming increasingly common in the health care industry. Although information technology (IT) poses many benefits to improving health care and ease of access to information, there are also security and privacy risks. Educating health care providers is necessary to ensure proper use of health information systems and IT and reduce undesirable outcomes. Objective: This study evaluated employees’ awareness and perceptions of the effectiveness of two IT educational training modules within a large publicly funded health care system in Canada. Method: Semi-structured interviews and focus groups included a variety of professional roles within the organisation. Participants also completed a brief demographic data sheet. With the consent of participants, all interviews and focus groups were audio recorded. Thematic analysis and descriptive statistics were used to evaluate the effectiveness of the IT security training modules. Results: Five main themes emerged: (i) awareness of the IT training modules, (ii) the content of modules, (iii) staff perceptions about differences between IT security and privacy issues, (iv) common breaches of IT security and privacy, and (v) challenges and barriers to completing the training program. Overall, nonclinical staff were more likely to be aware of the training modules than were clinical staff. We found e-learning was a feasible way to educate a large number of employees. However, health care providers required a module on IT security and privacy that was relatable and applicable to their specific roles. Conclusion: Strategies to improve staff education and mitigate against IT security and privacy risks are discussed. Future research should focus on integrating health IT competencies into the educational programs for health care professionals.

Purpose: To describe the unmet informational, psychological, emotional, social, practical, and physical needs and preferences for posttreatment survivorship care of individuals living with multiple myeloma to inform the development of relevant, person-centered, survivorship services. Methods: An exploratory, descriptive study using 2 focus groups with 14 participants, 6 to 49 months postdiagnosis. Results: Thematic analysis revealed 7 key themes: information needs, experience with health-care professionals, coping with side effects, communicating with family and friends, dealing with emotions, support needs, and living with the chronicity of myeloma. Participants described key characteristics of survivorship care relevant to their needs and indicated they would like a more whole of person approach to follow-up when the main treatment phases had completed. Conclusion: Participants in this study described unmet needs across a breadth of domains that varied over time. The development of flexible, person-centered approaches to comprehensive survivorship care is needed to address the considerable quality-of-life issues experienced by people living with multiple myeloma. Nurse-led care may offer 1 viable model to deliver enhanced patient experience—providing the vital “link” that people described as missing from their survivorship care.

Published: July 2017

Introduction As the revision number of shoulder arthroplasties increases, we focused on the difficulties of extracting or converting the humeral stem. The purpose of this multicentric study was to assess the outcomes and the radiographic results of a new, short, and convertible humeral stem (Aequalis Ascend™ Flex, Tornier SAS–Wright Medical Inc®, Bloomington, MN, USA), which could settle these complex revision problems. Methods Sixty-six primary shoulder replacements were enrolled with an average follow-up of 25.6 months (24–30.8 months). There were 24 reversed shoulder arthroplasty (RSA) and 42 anatomical shoulder arthroplasty. The functional outcomes were evaluated with the Constant-Murley score (CS) and the active range of motion. Humeral stems were radiologically analyzed at the last follow-up with special care to mechanical complications and bone resorption. Results The average CS improved from 30 preoperatively to 74 postoperatively ( P < .0001) for anatomical shoulder replacements and from 21 to 63 ( P < .0001) for RSA. The active anterior elevation and external rotation improved from 97° and 6° to 163° and 46°, respectively, for anatomical prosthesis ( P < .0001) and from 79° and 10° to 139° and 28°, respectively, for RSA ( P < .0001). No mechanical complication or loosening was reported. The comparison between postoperative and last follow-up X-rays showed a tendency to medial cortical bone thinning in some cases without any clinical relevance. Conclusion Two years follow-up of this short stem showed promising clinical and radiographic results without implant-related complication. Further X-rays study would be necessary.

ABSTRACTVymazalováite, Pd3Bi2S2 is a new platinum-group mineral discovered in the Komsomolsky mine of the Talnakh deposit, Noril'sk district, Russia. It forms small (from a few μm to 20–35 µm) inclusions or euhedral grains in intergrowths of polarite, sobolevskite, acanthite and unnamed (Pd,Ag)5BiS2 in aggregates (up to ~200 µm) in galena and rarely in chalcopyrite. It occurs with telargpalite, cooperite, braggite, vysotskite, sopcheite, stibiopalladinite, sobolevskite, moncheite, kotulskite, malyshevite, insizwaite, Au-bearing silver and the newly described mineral kravtsovite (PdAg2S) in association with pyrite, chalcopyrite and galena in vein-disseminated mineralization in skarn rocks. Synthetic vymazalováite is brittle; it has a metallic lustre and a grey streak. In plane-polarized reflected light, vymazalováite is creamy grey and appears slightly brownish against galena in the assemblage with chalcopyrite. It exhibits no internal reflections. Average reflectance values in air for natural and synthetic vymazalováite are (R natural, R synthetic in %) are: 46.35, 45.7 at 470 nm, 47.65, 47.45 at 546 nm, 48.5, 48.2 at 589 nm and 49.5, 49.0 at 650 nm. Seven electron probe micro-analyses of vymazalováite give an average composition: Pd 40.42, Bi 49.15, Ag 0.55, Pb 1.02, S 7.77 and Se 0.26, total 99.17 wt.%, corresponding to the empirical formula Pd3.05(Bi1.89Ag0.04Pb0.04)Σ1.97(S1.95Se0.03)Σ1.98 based on a total of 7 atoms per formula unit. The simplified formula is Pd3Bi2S2. The mineral is cubic, space group I213, with a = 8.3097(9) Å, V = 573.79(1) Å3 and Z = 4. The density calculated on the basis of the empirical formula and cell dimensions of synthetic vymazalováite is 9.25 g/cm3. The strongest lines in the powder X-ray diffraction pattern of synthetic vymazalováite [d in Å (I) (hkl)] are: 4.15(32)(200), 2.93(78)(220), 2.40(100)(220), 2.08(53)(400), 1.695(34)(422), 1.468(35)(440) and 1.252(31)(622). The structural identity of natural vymazalováite with synthetic Pd3Bi2S2 was confirmed by electron back-scatter diffraction measurements on the natural sample. This new mineral honours Dr Anna Vymazalová of the Czech Geological Survey, Prague.
