Peter Sloterdijk and the ‘Security Architecture of Existence’: Immunity, Autochthony, and Ontological Nativism
Authors: Sutherland Thomas
Published: May 2019

Centred on Foams, the third volume of his Spheres trilogy (2011, 2014, 2016), this article questions the privilege granted by Peter Sloterdijk to motifs of inclusion and exclusion, contending that, whilst his prioritization of dwelling as a central aspect of human existence (drawing in part upon the work of Martin Heidegger) provides a promising counterpoint to the dislocative and isolative effects of post-industrial capitalism, it is compromised by its dependence upon an anti-cosmopolitan outlook that views cultural distantiation as a natural and preferable state of human affairs, and valorizes a purported ontological security attained through defensive postures with respect to perceived foreigners or externalities. Sloterdijk’s conceptualization of culture as a kind of immune system, it is argued, although posited as a rebuke to models of essentialism and ethno-nationalism, provides ontological support to the xenophobic critiques of immigration that are today finding increasing currency.
Interpersonal effects of health-related social control: Positive and negative influence, partner health transformations, and relationship quality
Authors: Young Valerie J. , Burke Tricia J. , Curran Melissa A.
Published: May 2019

It is common for romantic partners to influence one another’s health maintenance behaviors. Previous research has examined positively and negatively framed social control messages to understand health behavior outcomes and relational affect; however, this study confirms and extends previous research by studying the associations between health transformations (from interdependence theory, health behaviors enacted for the partner) and relationship satisfaction. Data from a cross-sectional dyadic survey of heterosexual couples were analyzed using actor–partner independence models. As expected, dyadic results showed that positive social control was associated with greater healthy and fewer unhealthy partner transformations, whereas negative social control was associated with lower relationship satisfaction and more unhealthy transformations. Further, the breadth of partner health behaviors that individuals attempt to influence moderated the associations between social control and relationship satisfaction and health transformations. We discuss how the results from this study underscore the health implications associated with the nature and breadth of social control communication in romantic relationships.
Global brain volume reductions in a sub-chronic phencyclidine animal model for schizophrenia and their relationship to recognition memory
Authors: Doostdar Nazanin , Kim Eugene , Grayson Ben , Harte Michael K , Neill Joanna C , Vernon Anthony C
Published: May 2019

Background:

Cognitive deficits and structural brain changes co-occur in patients with schizophrenia. Improving our understanding of the relationship between these is important to develop improved therapeutic strategies. Back-translation of these findings into rodent models for schizophrenia offers a potential means to achieve this goal.

Aims:

The purpose of this study was to determine the extent of structural brain changes and how these relate to cognitive behaviour in a sub-chronic phencyclidine rat model.

Methods:

Performance in the novel object recognition task was examined in female Lister Hooded rats at one and six weeks after sub-chronic phencyclidine (2 mg/kg intra-peritoneal, n=15) and saline controls (1 ml/kg intra-peritoneal, n=15). Locomotor activity following acute phencyclidine challenge was also measured. Brain volume changes were assessed in the same animals using ex vivo structural magnetic resonance imaging and computational neuroanatomical analysis at six weeks.

Results:

Female sub-chronic phencyclidine-treated Lister Hooded rats spent significantly less time exploring novel objects ( p<0.05) at both time-points and had significantly greater locomotor activity response to an acute phencyclidine challenge ( p<0.01) at 3–4 weeks of washout. At six weeks, sub-chronic phencyclidine-treated Lister Hooded rats displayed significant global brain volume reductions ( p<0.05; q<0.05), without apparent regional specificity. Relative volumes of the perirhinal cortex however were positively correlated with novel object exploration time only in sub-chronic phencyclidine rats at this time-point.

Conclusion:

A sustained sub-chronic phencyclidine-induced cognitive deficit in novel object recognition is accompanied by global brain volume reductions in female Lister Hooded rats. The relative volumes of the perirhinal cortex however are positively correlated with novel object exploration, indicating some functional relevance.
So Easy to See: Muriel Rukeyser and Berenice Abbott’s unfinished collaboration
Authors: Kennedy-Epstein Rowena
Published: May 2019

This essay reassembles from archival materials the lost collaboration between Muriel Rukeyser and Berenice Abbott, So Easy to See, which pairs Abbott’s innovative Super-Sight photographs with Rukeyser’s poetic-theoretical discussions of ‘seeing’ in order to discuss lesbian desire, the atomic bomb, the relationship between art and science, and female genius. The work was repeatedly rejected by male editors and curators, who demeaned and undervalued the innovative nature of the project, in part because Abbott and Rukeyser dared to assert themselves as scientific experts; nevertheless, it is an intellectually rich and artistically innovative collaboration by two of the twentieth century’s most versatile artists. From the early 1940s through the 1960s, in a period in the U.S. defined by the elevation of the sciences over the arts, they shared a similar goal: to develop new methods for demonstrating the uses of and relationships between the arts and the sciences. Through their collaboration, Rukeyser and Abbott worked against accepted gendered and disciplinary boundaries, in order to show how ‘science and art meet and might meet in our time’ as sources of imaginative possibility and social progress. In doing so, they engendered questions about what kinds of collaborative and artistic practices are sanctioned, about the ontology of things and the everyday, about materialist philosophy and about the radical possibilities of interdisciplinarity. By making visible this lost collaboration, this essay participates in the recovery of an innovative and exciting modernist collaboration, and asks us to see both the lost potential of its inventiveness as well as to contextualise its disappearance. In order to see their work on ‘seeing’, we must also undertake an exploration into the cultural mechanisms that obfuscated it at mid-century.
The death of a virtuous woman? Proverbs 31.10-31, gnomic qatal, and the role of translation in the analysis of the Hebrew verbal system
Authors: Siegismund Kasper
Published: May 2019

This article draws attention to the phenomenon of translation-based interference in the analysis of Biblical Hebrew. It is argued that the so-called gnomic qatal only exists when we translate certain passages in a certain way. Based on Joüon’s approach to the verbs in Prov 31.10-31, it is demonstrated that it is possible to interpret the woman in the poem as deceased. Consequently, the predominant verbal forms in the passage ( qatal and wayyiqtol) are not gnomic, contrary to the almost universal rendering of the forms as present tense in modern translations. Rather, they have their usual anterior meaning. Other examples of translation-based interference in the analysis of Biblical Hebrew (including the question of the verbs in biblical poetry) are discussed, and a case is made for relative tense as the appropriate category for describing the semantic content of the basic opposition between the (non-volitive) finite verbal forms.
The Niphal as middle voice and its consequence for meaning
Authors: van Wolde Ellen
Published: May 2019

The central thesis of this article is that improved knowledge of the Niphal can offer us arguments in favour of (or against) certain meanings of verbs in biblical texts. Proceeding from general linguistic studies of middle voice to Biblical Hebrew linguistics, the differences between the active, reflexive, middle and passive voices are clarified. Subsequently, it is shown that the Niphal expresses neither the reflexive nor passive voice, but predominantly marks the middle voice. The Niphal describes an event in which the subject is concerned with itself, though not reflexively as a differentiated object, but as an undifferentiated middle, while reference to an external Agent is absent. These insights are applied to various texts and verbs in the Hebrew Bible, namely, 3 Niphals of the verb גמל‎ (‘wean’), 7 Niphals (feminine singular) of the verb טמא‎ (‘defile’), and 16 usages of אסף‎ Niphal in contexts of dying.
Mordecai’s dream in Esther—The Greek and Latin versions, character, and the tradition of interpretation
Authors: Thambyrajah Jonathan A
Published: May 2019

The book presently known as Esther was in antiquity identified as not only the book of Esther but also the book of Mordecai. The primacy of Esther or Mordecai in the book preserved by the Masoretic Text is ambiguous. It is, however, well known that there are additional components to the book of Esther, found in the Greek versions (LXX, Alpha Text) and the Vetus Latina. By examining Mordecai’s dream and its interpretations, found in these additions to Esther, this study concludes that the different versions of the text correspond to different traditions of interpretation of the book of Esther. In particular, these different traditions differ in their perception of whether the story’s protagonist is Esther or Mordecai.
Valuing leadership and love: David exceeding Samson
Authors: Herbst John William
Published: May 2019

Of all the characters of the book of Judges none has more in common with the David of the so-called ‘History of David’s Rise’ than Samson. A careful comparison of Judg. 13.1–16.3 with 1 Sam. 16–23 reveals numerous similarities between the two figures, including the way their slaying of lions presages their most striking acts, and the way in which Yahweh and Saul, respectively, use the prospect of marriage to manipulate them to attack Philistines. We also find parallels in their calls, relationship to the rûaḥ YHWH, relationship to family, and use of wisdom. These extensive similarities naturally lead us to consider the differences which may explain Samson’s failure and David’s success. David is a leader, while Samson acts solo; David is beloved while not loving anyone, while Samson loves without being loved himself. These observations support deuteronomistic ideology highlighting leaders and leadership, and devaluing human love for other humans.

Published: May 2019

In New York City (NYC), as in several other U.S. cities, pediatric occupant restraint laws exempt rear-seated passengers in vehicles-for-hire from those that apply to private vehicles. This study compares rear-seated infant, child, adolescent, and teen passenger restraint use and injury in taxis compared with other passenger vehicles. New York State Department of Health Crash Outcome Data Evaluation System (CODES) was analyzed for rear-seated pediatric passengers aged 0–19 years traveling in taxis ( n = 1,631) or other passenger vehicles ( n = 21,984) involved in a crash in NYC 2011–2013. CODES is a probabilistically linked data set comprising emergency department, hospitalization, and Department of Motor Vehicle crash data. Bivariate and multivariable logistic regression odds ratios (OR) are reported with 95% CI. Taxi passenger restraint use was lower than in other passenger vehicles (51.2% vs. 86.7%, p < 0.0001). Use of a child restraint for ages < 8 years was low (5.9%) and one-tenth that of other passenger vehicles. Multivariable adjusted odds of restraint use was 9.80 (8.2–11.7) for other passenger vehicles compared with taxis. Compared with passengers in other vehicles, passengers in taxi crashes were twice as likely to be moderately or severely injured ( p < 0.0001) and twice as likely to have traumatic brain injury ( p = 0.0070). This study documents lower restraint use and higher injury, including traumatic brain injury, for pediatric taxi passengers compared with other passenger vehicles. Improved data systems, surveillance, and enforcement are needed to improve restraint use and reduce injury in children and teens, particularly those in vehicles-for-hire.
Modeling Passing Maneuver Based on Vehicle Characteristics for In-Vehicle Collision Warning Systems on Two-Lane Highways
Authors: Diachuk Maksym , Easa Said M. , Hassein Udai , Shihundu Daniel
Published: May 2019

Modern vehicles are equipped with various sensors of high accuracy and sensitivity, based on which it is possible to implement passing collision warning systems (PCWS) for two-lane highways. In previous systems, the time required to complete the passing maneuver safely was formulated based on pre-established regression models. In this paper, this time is formulated based on actual vehicle characteristics. The new vehicle dynamics model for the PCWS prototype includes steering control and drivetrain models, and allows more accurate prediction of the required passing time. The geometry of the passing maneuver (for the case of an impeding truck), the main phases of the passing process, and the distances related to the conditions for predicting passing time are described. The interactions between the PCWS and driver actions are formulated. The steering control model is based on a two-dimensional perspective representation of the three-dimensional reality perceived by the driver. The drivetrain model, including inertial and mechanical losses in the drivetrain, considers automatic gear shift and the presence of a torque converter to simulate vehicle performance accurately. The proposed PCWS was tested using MATLAB Simulink.
The Decline of Child Sexual Abuse in Canada: Evidence From the 2014 General Social Survey
Authors: Shields Margot , Tonmyr Lil , Hovdestad Wendy E.
Published: May 2019

Objective:

To provide evidence of trends in child sexual abuse (CSA) in Canada.

Methods:

Using data from 15,801 males and 18,669 females who responded to the 2014 General Social Survey (GSS), we compared the prevalence of CSA by age cohorts. Age cohort patterns were examined for several sub-populations including males, females, Indigenous peoples, and people living in low-income households.

Results:

After an increase in the post-World War II period, there has been a decline in CSA in Canada since the early 1990s. Findings indicate a decline for both sexes; although, the evidence is more compelling for females. There is also evidence of a decline for Indigenous peoples, for those living in low-income households, and regardless of the relationship to the perpetrator (i.e., family member, a teacher/professor/tutor, a babysitter, a nanny, other non-family member but known to the respondent, or a stranger).

Conclusions:

In Canada, evidence from 3 retrospective population surveys suggests a decline in CSA since the early 1990s. However, given the associated harm, continued progress to the eradication of CSA is essential.
Synthesis of a novel hyperbranched polysiloxane with amidogen groups and the characteristics of a polymer alloy blend with bismaleimide resin
Authors: Jia Yuan , Liu Zhen , Wang Xuan , Li Beibei
Published: May 2019

To improve the thermal resistance, mechanical and tribological properties of a bismaleimide (BMI) resin, a novel hyperbranched polysiloxane with terminal functional amidogen groups (HBPSi-NH2) was prepared through a convenient one-step transesterification process. The raw materials included N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (KH-792) and excessive neopentyl glycol. Both Fourier transform infrared spectroscopy and nuclear magnetic resonance spectra were collected to determine the chemical structure of the HBPSi-NH2. The novel prepared HBPSi-NH2 was then used as a modification phase to blend with BMI (HBPSi-BMI), and the thermal properties of the HBPSi-BMI-cured resins were investigated by differential scanning calorimetry and thermogravimetry. The mechanical and tribological properties of HBPSi-BMI were also researched. The results suggested that both the thermal properties and the mechanical properties of HBPSi-BMI increased with the appropriate addition of HBPSi.
Comparison among the environmental impact of solid state and fusion welding processes in joining an aluminium alloy

Published: May 2019

The life-cycle assessment methodology was used to evaluate the environmental impact of friction stir welding of AA5754-H114 aluminium alloy sheets. Other works in literature considered the environmental impact of friction stir welding, but in this study the influence of different process parameters on midpoint category impacts were analysed. Friction stir welding was performed under different values of rotational and welding speeds. Moreover, pin tool wear and mechanical properties of joints were also evaluated. The pre- and post-processing stages were also considered. Raw materials, energy and all inputs associated with each stage of product life cycle were collected and evaluated to analyse the environmental impact index. The results showed that, irrespective of the rotational speed, the lowest welding speed investigated leads to the highest energy consumption and, consequently, to the highest values of the midpoint category impact. On the contrary, at the highest welding speed, the environmental impact assumes the lowest values. By concerning the rotational speed, its effect on the midpoint category impact is strongly reduced compared with the one given by the welding speed. A performance index, obtained by considering both the midpoint category impact and ultimate tensile strength of the joints, was also defined. Finally, the environmental sustainability of friction stir welding was compared with two different fusion welding technologies, namely gas tungsten arc welding and laser beam welding. The results showed that friction stir welding was characterized by midpoint category impacts much lower than those of the gas tungsten arc welding, while such discrepancies decreased with the laser beam welding.
Abrupt Alnus population decline at the end of the first millennium CE in Europe – The event ecology, possible causes and implications

The study, based on the examination of 70 published and unpublished pollen profiles from Poland and supplementary data from the surrounding regions, shows that an abrupt, episodic Alnus population decline at the end of the first millennium CE was a much more widespread event than has been previously reported, spanning large areas of the temperate and boreal zones in Europe. The data from Poland suggest that the decline was roughly synchronous and most likely occurred between the 9th and 10th centuries, with strong indications for the 10th century. The pollen data indicate that human impacts were not a major factor in the event. Instead, we hypothesize that one or a series of abrupt climatic shifts that caused floods and droughts at the end of the first millennium CE could have initiated this ecological disturbance, leading to a higher vulnerability of the alder trees to a pathogen outbreak. Following current observations of the decline of alder stands in Europe due to a Phytophthora outbreak, we suggest that a similar process may have occurred in the past. This study provides insight into long-term alder (mainly Alnus glutinosa) dynamics in a condition of climate change and illustrates its great resilience, enabling the natural, successful regeneration of alder stands after critical diebacks if environmental conditions improve. Our finding that the Alnus pollen decline reflects a roughly synchronous event indicates that the decline could be used as an over-regional chronostratigraphic marker for 800–1000 CE in pollen diagrams from a large part of the European Lowland.

Multicenter Early Radiographic Outcomes of Triplanar Tarsometatarsal Arthrodesis With Early Weightbearing
Authors: Ray Justin J. , Koay Jennifer , Dayton Paul D. , Hatch Daniel J. , Smith Bret , Santrock Robert D.
Published: May 2019

Background:

Hallux valgus is a multiplanar deformity of the first ray. Traditional correction methods prioritize the transverse plane, a potential factor resulting in high recurrence rates. Triplanar first tarsometatarsal (TMT) arthrodesis uses a multiplanar approach to correct hallux valgus in all 3 anatomical planes at the apex of the deformity. The purpose of this study was to investigate early radiographic outcomes and complications of triplanar first TMT arthrodesis with early weightbearing.

Methods:

Radiographs and charts were retrospectively reviewed for 57 patients (62 feet) aged 39.7 ± 18.9 years undergoing triplanar first TMT arthrodesis at 4 institutions between 2015 and 2017. Patients were allowed early full weightbearing in a boot walker. Postoperative radiographs were compared with preoperative radiographs for hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position (TSP), and lateral round sign. Any complications were recorded.

Results:

Radiographic results demonstrated significant improvements in IMA (13.6 ± 2.7 degrees to 6.6 ± 1.9 degrees), HVA (24.2 ± 9.3 degrees to 9.7 ± 5.1 degrees), and TSP (5.0 ± 1.3 to 1.9 ± 0.9) from preoperative to final follow-up ( P < .001). Lateral round sign was present in 2 of 62 feet (3.2%) at final follow-up compared with 52 of 62 feet (83.9%) preoperatively. At final follow-up, recurrence was 3.2% (2/62 feet), and the symptomatic nonunion rate was 1.6% (1/62 feet). Two patients required hardware removal, and 2 patients required additional Akin osteotomy.

Conclusion:

Early radiographic outcomes of triplanar first TMT arthrodesis with early weightbearing were promising with low recurrence rates and maintenance of correction.

Level of Evidence:

Level IV, retrospective case series.
Unhealthy Fun: Food and Beverage References in Comedy Series
Authors: Mayrhofer Mira , Naderer Brigitte , Binder Alice
Published: May 2019

We analyzed comedy series for food and beverage references, with particular attention to their type of presentation, along with the characteristics of actors associated with the references. Because the generally positive tone of comedy series can exert affective influence over audiences, the result that clearly unhealthy products appeared more often (food: 51.6%; beverage: 40.5%) than clearly healthy ones (food: 11.2%; beverage: 19.6%) could be especially problematic. Moreover, women (56.5%; men: 47.4%) and African American characters (62.7%; Caucasians: 51.5%; Other: 44.7%) were significantly more often associated with unhealthy foods, which could prompt stereotypes of such individuals.
Relevance of the features regarding the performance of booking websites
Authors: Foris Diana , Tecau Alina Simona , Hartescu Madalina , Foris Tiberiu
Published: May 2019

Nowadays, the tourists increasingly prefer to plan their travels using online search engines, to the detriment of classical travel agencies. A well-designed and well-managed booking website can satisfy the tourists’ needs, whereas a less intuitive one can make them dissatisfied. The search engine developers cannot develop an effective and efficient booking website which satisfies the users’ needs, creates a favorable experience for them, and influences their intention to purchase, without understanding the users’ needs regarding the search engines attributes and features. This study applies a quantitative research, collects primary data, and investigates how booking websites can move from a basic to a sophisticated online presence. The aim of the analysis is to provide an insight regarding the tourists’ preferences and their interface needs, as well as the filters and the options that may help them find the most relevant results for the chosen destinations. The study develops a comprehensive performance evaluation model for booking websites using specific attributes and features of the tourism industry. This model includes usability and functionality dimensions that have been identified by analyzing six booking websites, three used at the international level (Booking, Priceline, and Hotwire) and three used only in Romania (Vola, Infoturism, and Carta), and correlated with the customers’ needs regarding booking websites and hotel website evaluation. The results are useful for booking website developers and can be used to adapt their user interfaces, making them far more user-friendly. Suggestions are made regarding how to improve the performance of booking websites and potential ways for future research are discussed.
Job demands and control and sickness absence, disability pension and unemployment among 2,194,692 individuals in Sweden
Authors: Norberg Jan , Alexanderson Kristina , Framke Elisabeth , Rugulies Reiner , Farrants Kristin
Published: May 2019

Background: Knowledge is needed on associations between job demands and job control and long-term sickness absence (SA) and unemployment. We explored associations of job demands and job control with SA/disability pension (DP) and unemployment among women and men in paid work. Methods: We included all 2,194,694 individuals living in Sweden in 2001, aged 30–54 years, and in paid work. The Swedish Job Exposure Matrix (JEM) was used to ascertain levels of job demands and job control. Individuals were categorized into nine groups based on combinations of high, medium, or low values on both demands and control. Using multinomial logistic regression, we estimated odds ratios (OR) with 95% confidence intervals (CI) for the association of job demands and job control with risk of long-term SA/DP (>183 net days) and long-term unemployment (>183 days). Results: Regarding SA/DP, among women the risk was highest for those in occupations with low demands and low control (OR=1.32; 95% CI: 1.28–1.36), whereas among men the risk was highest among those in occupations with high demands and low control (OR=1.22; 1.11–1.34). Regarding unemployment, among women the risk was highest among those in occupations with low demands and medium control (OR=1.30; 1.24–1.37), whereas among men the risk was highest for those in occupations with low demands and high control (OR=1.54; 1.46–1.62). Conclusions: Using a JEM among all in a population rather than for specific occupations gives a more comprehensive view of the associations between job demands/job control and long-term SA/DP and unemployment, respectively.

Objective:

To investigate the impact of premature extraction of primary teeth (PEPT) on orthodontic treatment need in a cohort of children participating in the Born in Bradford (BiB) longitudinal birth cohort.

Design:

Observational, cross-sectional cohort.

Participants:

We aim to recruit 1000 children aged 7–11 years: 500 with a history of PEPT and 500 matched non-PEPT controls.

Methods:

After informed consent/assent, orthodontic records will be collected, including extra and intra-oral photographs and alginate impressions for study models. Participants will also complete a measure of oral health-related quality of life (COHIP-SF 19). The records will be used to quantify space loss, identify other occlusal anomalies and assess orthodontic treatment need using the Index of Orthodontic Treatment Need. For each outcome, summary statistics will be calculated and the data for children with and without PEPT compared. The records of the children identified to be in need of orthodontic treatment will be examined by an expert orthodontic panel to judge if this treatment should be undertaken at the time of the records or delayed until the early permanent dentition. Collecting robust records in the mixed dentition provides the clinical basis to link each stage of the causal chain and enable the impact of PEPT on orthodontic need to be characterised. This study is the first to provide the foundations for future longitudinal data collection allowing the long-term impact of PEPT to be studied.
Legitimizing entrepreneurial success in an environment of Tall Poppy syndrome: Lessons from celebrity entrepreneurs in New Zealand
Authors: Kirkwood Jodyanne , Warren Lorraine
Published: May 2019

In this article, we examine the phenomenon of Tall Poppy syndrome (TPS) in relation to entrepreneurship in New Zealand. TPS is based on the concept that some peoples’ success elevates or distinguishes them from others, resulting in envy from others. TPS has been highlighted as an important element of New Zealand’s culture. This may clash with government initiatives, which often focus on building a high profile for aspirant entrepreneurs. In this article, we carry out a qualitative study into 11 such ‘celebrity’ entrepreneurs in New Zealand. The key question of our study is how being held up as a celebrity affects their practice. By introducing the celebrity element into our study, we contribute further understanding about the processes of social legitimacy for entrepreneurs. This has important implications for policy and practice, because if entrepreneurs are ‘allowed’ to be successful, this may encourage them to influence another generation of entrepreneurs to challenge TPS.
Computer modeling and simulation for undersaturated primary drive recovery mechanism
Authors: Gyan Patricia Semwaah , Xie Congjiao , Brantson Eric Thompson , Atuahene Samuel
Published: May 2019

The focus of this article is to test the capability of a three-dimensional undersaturated numerical reservoir simulator developed for prediction of actual field performance cases. The simulator development employs unconditional stable Crank–Nicolson second order in time approximation discretization scheme and preconditioned conjugate gradient iterative solver for the derived fluid flow equation. Furthermore, formation volume factor as a function of cell pressure is computed at each time step until bubble-point pressure is reached. The reservoir model is then coupled with a horizontal wellbore model in the simulator by placing a well optimally at the center of its drainage volume. The numerical simulation results show that the numerical solutions improve significantly with the addition of grid blocks. Graphical visualization surface and contour map plots show rapid and continuous average reservoir pressure depletion with time for an earliest possible determination and characterization of primary drive mechanisms. The rate of pressure depletion and recovery factor estimation (1.52%) are the two main characteristics used to identify depletion drive or rock and liquid expansion drive as the best-fit prospective drive for the reservoir model. The total cumulative production of 170,000 stock-tank barrels (MSTB) recovered in 1390 days is in agreement with the field data used. Sensitivity analyses with the numerical simulator illustrated the key impact of reservoir parameters on pressure depletion with less computational expensiveness. Finally, material balance incremental (0.995) and cumulative (1.005) error checks validate the simulator robustness within an acceptable tolerance limit.
Sliding mode control design for stabilization of underactuated mechanical systems
Authors: Idrees Muhammad , Ullah Saif , Muhammad Shah
Published: May 2019

Stabilization of underactuated mechanical systems is one of the fundamental benchmark problem in the field of control theory. In this article, a hierarchical sliding mode control based on state-dependent switching gain is proposed for stabilization of underactuated mechanical systems. This controller is based on the so called first-level and second-level sliding surfaces. The asymptotic stability of these surfaces is proved by the Lyapunov stability theory. The proposed control technique is applied to two nonlinear underactuated mechanical systems and its feasibility is verified by numerical simulation. The proposed controller efficiently tackles the bounded external disturbance and shows robust performance. The convergence rate of the proposed controller is much faster as compared with the conventional decoupled sliding mode control and the integral sliding mode control.
A manufacturing-oriented error modelling method for a hybrid machine tool based on the 3-

RS parallel spindle head

Published: May 2019

Five-axis hybrid machine tools are widely used due to the advantages of high speed, high precision, and good performance in the aviation and aerospace manufacturing industry. Many scholars have studied the basic theories and key technologies along with the widespread attention of academia and industry thereon. An integrated geometric error modelling method, under the unified coordinate system framework for a general five-axis hybrid machine tool based on a 3-PRS parallel spindle head, is proposed. The kinematic inverse model of a hybrid machine tool is built using a vector chain method. On the basis of the analysis of the various error sources, an integrated geometric error model is developed based on perturbation theory. Then, the influence of each error source of a hybrid machine tool is investigated at the end-effector. Screw theory is applied to research error source separation for the 3-PRS parallel spindle head of a hybrid machine tool, and a sensitivity analysis of the error sources is undertaken using statistical methods. Based on this, the compensable error sources and non-compensable error sources of a hybrid machine tool are separated successfully. The non-compensable error sources must be strictly controlled in the process of design and manufacture, while the compensable error sources can be compensated inexpensively by software after reaching some degree of accuracy in the design and manufacture. This research provides a theoretical reference for this kind of machine tool design and its use in manufacturing.
Air-to-ground multimodal object detection algorithm based on feature association learning
Authors: Yang Dongfang , Liu Xing , He Hao , Li Yongfei
Published: May 2019

Detecting objects on unmanned aerial vehicles is a hard task, due to the long visual distance and the subsequent small size and lack of view. Besides, the traditional ground observation manners based on visible light camera are sensitive to brightness. This article aims to improve the target detection accuracy in various weather conditions, by using both visible light camera and infrared camera simultaneously. In this article, an association network of multimodal feature maps on the same scene is used to design an object detection algorithm, which is the so-called feature association learning method. In addition, this article collects a new cross-modal detection data set and proposes a cross-modal object detection algorithm based on visible light and infrared observations. The experimental results show that the algorithm improves the detection accuracy of small objects in the air-to-ground view. The multimodal joint detection network can overcome the influence of illumination in different weather conditions, which provides a new detection means and ideas for the space-based unmanned platform to the small object detection task.

Métodos: se realizaron seis grupos focales: dos con mujeres embarazadas; dos con madres de niños <3 años de edad, y dos con hombres quienes en los últimos tres años fueron padres. Resultados: la hegemonía masculina en el contexto familiar y en las instituciones de salud, dificulta la autonomía y el poder de decisión de las mujeres sobre su salud reproductiva. Esto impacta directamente en la búsqueda de atención durante el embarazo y el parto. Conclusiones: la falta de autonomía y de poder de decisión femenino se relaciona indirectamente, con resultados adversos del embarazo. Estos hallazgos son útiles para orientar el diseño de estrategias que promuevan el empoderamiento de las mujeres y la equidad de género en el contexto de los servicios y programas comunitarios y llamar la atención de tomadores de decisiones hacia la presencia, de factores no-médicos de la muerte materna en comunidades indígenas.

Background:

The goal of this study was to assess patient perspectives and satisfaction with the MiniMed 670G insulin pump. Those participants who used the pump as part of a hybrid closed loop were also asked to provide their views on the automatic feature (auto mode).

Methods:

Adults with type 1 diabetes mellitus using the Medtronic™ 670G pump were asked about their experience with the device using a semi-structured survey developed by the research team. Responses were quantified to identify emergent themes.

Results:

Seventeen participants used the pump as part of a hybrid closed loop system, while four participants used the pump in combination with a nonintegrated continuous glucose monitoring system. Overall, participants indicated a high level of satisfaction with the pump (14/21) mostly because of improvements in blood glucose (BG) control (15/21). Least liked features were physical design and structure (6/21), frequency of user input (5/21), alert frequency (4/21), and difficulty of use (3/21). Those using the hybrid closed loop were satisfied with the auto mode feature (11/17), mostly because of improvements in BG control (9/17). The least liked features of the auto mode technology were that blood glucose levels remained elevated (5/17) and the frequency of alerts (4/17).

Conclusion:

Participants indicated a high level of satisfaction with the pump and its auto mode featured mostly because of improvements in BG control. They also pointed out some key aspects of the device that are of potential clinical or commercial relevance. Additional research is needed to further evaluate users' perspectives on this new device.

Epithelioid sarcoma is a very rare tumor, comprising less than 1% of all soft tissue sarcoma. Due to its rarity and benign presentation, it is often misdiagnosed. We present a case of epithelioid sarcoma mimicking coronary artery bypass grafting post-operative keloid. Current literature suggests the management for epithelioid sarcoma to include surgery and adjuvant radiation. In this patient, chest wall reconstruction was done using titanium mesh and muscle flaps. Post-operative radiation was given and computerized tomography scan was evaluated 3 months after reconstruction.

Intractable ulcers often occur following primary diseases and have a significant impact on the quality of life of affected subjects. The medical treatments now available include compression and continuous debridement or additional interventions such as advanced wound dressings, local or systemic antibiotics with a mild benefit for the patients in the long term. In this report, we describe the use of autologous micrografts obtained by Rigenera® procedure in the management of two cases of intractable ulcers showing good outcomes for both patients approximately after 30 days from intervention. In the first case, a 74-year-old male with a diagnosis of Fournier’s gangrene who underwent several interventions showed a rapid wound epithelization after micrografts application. In the second case, a 63-year-old male affected by a left hallux ulcer with a diagnosis of chronic osteomyelitis also showed a gradual reduction in the ulcer approximately after 1 month from micrografts application.

Monoclonal gammopathy is a premalignant condition associated with an abnormal circulating immunoglobulin indicative of an expanded B cell clone. Apart from monitoring, no other intensive management is prescribed in these cases. Periodic bone marrow biopsies when free light chain imbalances are detected are used to spot incidental cases of multiple myeloma. New reports have suggested the existence of a monoclonal gammopathy of renal significance where a circulating antibody and normal bone marrow biopsy results may be associated with proteinuric renal disease due to monoclonal immunoglobulin deposition. We report a case of a 65-year-old male with an immunoglobulin G kappa monoclonal gammopathy of undetermined significance, chronic kidney disease, proteinuria, and an initial inconclusive renal biopsy. His chronic kidney disease worsened with persistence of 0.5 g of proteinuria. Given the finding of ongoing Bence Jones proteinuria, a repeat renal biopsy was done revealing monoclonal immunoglobulin G kappa deposition disease. Bone marrow biopsy showed 20% plasma cells that could be consistent with smoldering myeloma. The patient’s renal disease has stabilized after starting treatment for the monoclonal gammopathy of renal significance. This case illustrates the importance of renal biopsy in making the diagnosis of monoclonal immune deposition disease and monoclonal gammopathy of renal significance.

Background

The combination of higher stress and higher obesity rates suggests that Latino youth in the United States may be a population at particular risk for obesity-related adverse health outcomes. The objective of this article is to describe the feasibility, acceptability, and quantitative stress-related outcomes of a 6-week pilot lifestyle intervention using guided imagery (GI) council in order to reduce risk factors for obesity-related disease.

Methods

Seventeen urban, adolescents (12 females/5 males, 16 Latino, age 17 ± 1 years, grades 9–12, body mass index 22 ± 4) participated in the 6-week, after-school pilot intervention. The intervention consisted of three, 75-minute after-school sessions delivered weekly for 6 weeks. The 3 weekly sessions included 1 session each of nutrition education, physical activity education and practice, and GI delivered in council, a facilitated group process based on indigenous practices. Feasibility and acceptability were assessed by attendance and qualitative exit interview. Stress outcomes included salivary cortisol and perceived stress.

Results

The pilot intervention was found to be feasible to deliver in an after-school setting. The GI and council group format were well liked. A 31% reduction in salivary cortisol was observed following the stress-reduction GI sessions. Diurnal cortisol patterns did not change across the intervention, but change in perceived stress was correlated with change in cortisol awakening response.

Conclusions

The intervention was feasible to deliver and highly acceptable. Acute reduction in salivary cortisol was seen following group GI, while no change was seen in daily cortisol patterns. These results support the development of a full 12-week intervention using GI council to reduce obesity-related disease risk.
Return to Sport After the Surgical Treatment of Superior Labrum Anterior to Posterior Tears: A Systematic Review
Authors: Abdul-Rassoul Hussein , Defazio Matthew , Curry Emily J. , Galvin Joseph W. , Li Xinning
Published: May 2019

Background:

Controversy exists as to the optimal treatment of superior labrum anterior to posterior (SLAP) tears in athletes. There are no systematic reviews evaluating return-to-sport (RTS) rates after arthroscopic SLAP repair and biceps tenodesis.

Purpose:

To compare the overall RTS rates in patients with primary type 2 SLAP tears who were managed with arthroscopic SLAP repair versus biceps tenodesis.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by searching the MEDLINE (PubMed), Embase (Elsevier), and Cochrane Library databases. Inclusion criteria were clinical studies that evaluated RTS rates after arthroscopic SLAP repair, arthroscopic SLAP repair with partial rotator cuff debridement, and biceps tenodesis. The studies were analyzed for quality and inclusion in the final analysis. Data relevant to RTS rates were then extracted and compiled, and outcomes were compared.

Results:

Of the 337 studies initially identified, 15 (501 patient-athletes) met inclusion criteria. These consisted of 195 patients who underwent isolated arthroscopic SLAP repair (mean age, 31 years; mean follow-up, 3.2 years), 222 patients who underwent arthroscopic SLAP repair with partial rotator cuff debridement (mean age, 22 years; mean follow-up, 5.1 years), and 84 patients who underwent biceps tenodesis (mean age, 42 years; mean follow-up, 3.3 years). The overall RTS rates were high for all 3 procedures (SLAP repair, 79.5%; SLAP repair with rotator cuff debridement, 76.6%; biceps tenodesis, 84.5%), with biceps tenodesis having the highest overall rate. Biceps tenodesis also had the highest RTS rate at the preinjury level (78.6%) compared with SLAP repair (63.6%) and SLAP repair with rotator cuff debridement (66.7%).

Conclusion:

Primary arthroscopic SLAP repair, arthroscopic SLAP repair with partial rotator cuff debridement, and biceps tenodesis all provide high RTS rates. Biceps tenodesis as an operative treatment of primary SLAP lesions may demonstrate an overall higher RTS rate when compared with traditional SLAP repair in older athletes. More, higher level studies are needed that control for age, level of activity, and type of sport (overhead vs nonoverhead) to determine the efficacy of biceps tenodesis as a primary alternative to arthroscopic SLAP repair in young athletes who present with type 2 SLAP tears.
