Reinventing the Self: NXIVM’s Promises, Secrets, and Lies
Authors: Raine Susan
Published: February 2022

In this article, I examine the multilevel cultic organization NXIVM, using Susie Scott’s (2011) reinventive institution thesis—an update of Erving Goffman’s (1961) work on total institutions. Scott’s (2011) work addresses some of the broader sociocultural shifts that have fostered a turn inward toward self-improvement in the quest for new, transformative identities. Such shifts have created a proliferation of movements, organisations, and groups— including NXIVM—that offer ideologies and practices that promise to fulfill these reinventive goals. Offering opportunities for macrolevel and microlevel analyses, I employ Scott’s model not only to situate NXIVM within this cultural milieu, but also to examine some of the specifics of its structure, the nature of interpersonal relationships, and the promises that the movement and its founder, Keith Raniere, made. Moreover, as Scott’s (2011) work reveals, attractive as they may be, reinventive institutions incorporate structures of power thatrender them far from benign. Hence, by drawing on Scott’s postulations, I examine features of NXIVM that illustrate both the promises and problems of reinventive institutions. Moreover, I discuss those aspects of NXIVM that have more in common with total institutions than reinventive ones, demonstrating that, at least in this case, the two types of institution may operate within one organisation. To explore both reinventive and totalistic characteristics, I discuss some of the key features of the following NXIVM organisations: Executive Success Programs (ESP), Jness, the Society of Protectors (SOP), and Dominus Obsequious Sororium (DOS). Keywords: NXIVM, Keith Raniere, reinventive institutions, self-actualization, identity

Bioclimatic classification of 19 stations in India in terms of cumulative heat stress
Authors: MAJUMDAR N. C. , PICHAN G. , LAL B. , MALHOTRA M. S.
Published: February 2022

The paper makes an attempt to outline a rational approach towards bioclimatic classification of the climates of Indian stations, in relation to human comfort and efficiency, keeping in view the nature and quantum of relevant available meteorological data. A simple and practical index of monthly cumulative heat stress has been defined and termed as Monthly Excess Maximum Effective Temperature days (MEMET), which has been found to correlate very well with Excess Discomfort Index Hour-Days based on mean hourly values of dry and wet bulb temperatures during daylight hours. This index has been utilised for grading 19 Indian stations in descending order of cumulative discomfort for (i) the hottest month of the year, (ii) average of the three hottest months of the year, and (iii) average-of eight months from March to October. Tentative assessment of the air conditioning needs has also been made on a monthly basis in terms of MEMET values. Findings are applicable to average acclimatised Indian adult males in normal summer clothing, resting or engaged in sedentary duties indoors with an average wind speed of 150 ft/min (2.7km/hr).
Temperature distribution over Bombay during a cold night
Authors: MUKHERJEE A. K. , DANIEL C. E. J.
Published: February 2022

A mobile temperature survey of Bombay and Greater Bombay was conducted in the early hours of 11 January 1975. The survey shows a 'heat Island' over the Malabar Hill, Girgaum and Cuffee Parade area with a maximum temperature difference of about 11° between the urban and the almost rural suburbs. The horizontal temperature distribution is found to be influenced by proximity to the sea, concentration of population, tall buildings and industry and the prevailing wind field. Vertical temperature profile measurements over the Worli Television tower indicate the top of presumably the first inversion layer in this area to be around 127 m on this day.

We formulate and study the nonlocal and local least gradient problem, which is the Dirichlet problem for the 1-Laplace operator, in the non-Euclidean setting of Carnot groups. We study the passage from the nonlocal problem to the local problem as the range of the interaction goes to zero. During this procedure, we prove a total variation estimate of independent interest and give an existence result for the local problem.
Odontoid Fractures: A Standard Review of Current Concepts and Treatment Recommendations
Authors: Nourbakhsh Ali , Hanson Zachary C.
Published: February 2022

Odontoid fractures represent the most common fractures involving C2 and the most common cervical spine fractures in patients older than 65 years. Despite their increasing frequency, optimal management of these injuries remain a subject to debate. Although types I and III injuries have relatively good healing potential with nonsurgical treatment, type II fractures carry a higher risk for nonunion. In particular, elderly patients are at risk for nonunion or fibrous malunion after nonsurgical treatment; however, increased medical comorbidities and poor bone quality also increase the risks of surgery in this cohort. The high morbidity and mortality associated with these injuries has made it an area of particular interest among spine surgeons. The purpose of this review was to summarize the pathophysiology, evaluation, and diagnosis of these injuries and to review controversies in management and considerations for treatment based on the most recent available literature.
Movement Is Life—Optimizing Patient Access to Total Joint Arthroplasty: Obesity Disparities
Authors: Sabesan Vani J. , Rankin Kelsey A. , Nelson Charles
Published: February 2022

Thirty five percent of the American population is considered obese (body mass index [BMI] > 30). Obesity disproportionately affects African Americans, Hispanics, and women. Obesity is associated with postoperative complications, including wound complications, infections, and revision total joint arthroplasty (including total hip arthroplasty and total knee arthroplasty). Current BMI benchmarks (many institutions rely on a BMI of 40) selectively preclude patients from having surgery. Patients in these underserved populations can be optimized through the lens of shared decision making through the assessment of food security (eg, food deserts and food swamps), ability to afford healthy food, knowledge of social safety net and community resources to access healthy food, nutrition and weight loss referrals to programs that accept all forms of insurance, weight loss measurements as a percentage of body weight lost instead of BMI cutoffs, pharmacologic modalities, and bariatric surgery.
Occupational Hazards for the Practicing Orthopaedic Surgeon: A Standard Review
Authors: Patel Kishan , Judd Hyrum , Harm Richard G. , Spanyer Jonathon
Published: February 2022

Orthopaedic surgeons are exposed to various occupational hazards in a busy daily practice which can cause potential physical injury and additional mental stress. By better understanding the hazards that are faced in the operating theater and the preventive measures that can be taken to avoid injury, orthopaedic surgeons can remain effective in their patient care duties. Infectious exposures, radiation exposure, noise pollution, chemical hazards, and physical demands are frequently encountered at the time of surgery and should be attenuated or avoided when possible. Simple preventive measures can prolong careers and protect the operating surgeon from musculoskeletal injuries and even solid organ damage and malignancy. Important consideration should be taken to recognize potential occupational hazards and act prophylactically before injury has occurred, and constant vigilance is required to avoid additive injury over time from physical and chemical insults.

Published: February 2022

Under nutrition in mothers is a major factor which results in abnormal or reduced growth of fetus, low birth weight (LBW), neonatal illness and infant death Objective: To determine the association of dietary factors with birth weight of neonates Methods: This cross-sectional study was conducted on 100 mothers, divided into 2 groups, one having normal weight (NW) infants and other having LBW infants. Data regarding their dietary habits and anthropometric measurements were taken Results: The results showed that 29 mothers of NW babies were older child born with NW, 21 mothers of NW babies were not older child born with NW, whereas 29 mothers of LBW babies were older child born with NW, 21 mothers of LBW babies were not older child born with NW. There was an insignificant association (p=1.000) between education and neonate’s birth weight as p-value is greater than 0.05. Conclusions: The rate of LBW were more affected by their food choices (lack of knowledge, improper antenatal care, less consumption of milk and protein and also fruits and vegetable) as compared to mothers with NW babies, other confounding determinants such as illiteracy rate, poor maternal nutrition and lifestyle factors, no knowledge regarding balanced diet and supplementation among pregnant females leads to prevalence of LBW infants.

Engaging Citizens and Transforming Designers: Analysis of a Campus- Community Partnership Through the Lens of Children’s Rights to Participate
Authors: Derr Victoria , Malinin Laura , Banasiak Meredith
Published: February 2022

While an engaged citizenry is often the goal of community service learning, the rights of children to be active agents in this process are largely considered in a separate academic literature. Yet community service learning and children’s participation share much in their goals and approaches to engagement. This paper analyzes a campus-community partnership between undergraduate environmental design and middle school applied science students. The partnership began as a way to promote participatory design processes for the redesign of a middle school and evolved to a proactive co-design program. We describe the goals and approaches to service-learning employed through the partnership, and critique the evolution of the program through the realm of a participation model that has emerged from three decades of children’s participation research. By analyzing a campus-community partnership through this framework, we hope to deepen the discourse on approaches to and evaluation of successful service-learning programs.

A Test of Student Grade Satisficing by Experimentally Inducing Time Stress
Authors: Petrow Gregory A.
Published: February 2022

Scholars studying scholastic achievement in higher education find that students have specific course grades in mind that satisfy their desires for academic performance. When students believe that they are on-track to achieve those grades, they divert resources to other endeavors. This paper tests a resulting hypothesis: Students balance higher grades on easier assignments with lower grades on more difficult ones. After experimentally inducing time stress by assigning students to participate in an experiential learning exercise, those busier with volunteer work did balance their higher grades on the easier, experiential assignments, against lower ones on the course exams. Additionally, the time stress produced a strong interaction effect. Among the busier students, the time stress reduced their course grades (those not related to the experiential learning), while among the less busy, those grades increased. Instructors should be aware that some course activities are less linked to learning than others. The educational consequence of student grade satisficing is that when instructors offer more credit for easier activities, which are less linked to student learning, they may be reducing learning overall. The role of grade satisficing in reducing students’ acquisition of knowledge is an under-explored topic, but it has powerful implications for student learning.

Published: February 2022

The artificial vision system (AVS) uses image analysis methods that can interpret images and identify nutritional deficiency symptoms in plant, even in the early stages of development. The objective of this study was to propose methods of image processing using analysis by texture to identify the deficiency of calcium (Ca) in maize (Zea mays L.) plants grown in nutrient solution. Plants were grown in nutrient solution in a greenhouse. Calcium doses were 0.0; 1.7; 3.3 and 5.0 mM of Ca, with four replications. Plant and leaf images were sampled at three main stages of maize development: V4 (plants with four leaves fully developed), V6 (plants with six leaves fully developed) and V8 (plants with eight leaves fully developed). Sampled material was split into (i) index leaf (IL) of the growing stage (V4 = leaf 4, V6 = leaf 6, and V8 = leaf 8), and (ii) new leaf (OL), both to image capture and chemical analysis. Such leaves were scanned, processed by the AVS and chemically analyzed. The texture methods used by the AVS to extract deficiency characteristics in the leaf images were: Volumetric Fractal Dimension (VFD), Gabor Wavelet Energy (GWE) and VFD with canonical analysis (VFDCA). The amount of Ca in the solution resulted in variation in the concentration of Ca in NL and IL, allowing the observation of typical symptoms of Ca deficiency.

Carrot (Daucus carota) is one of the most important vegetables in the world. Cow urine is a fertilizer available in rural areas and can be used in agriculture. However, there are no indications of the best dose to be used in carrots. The authors aimed with this work to evaluate different concentrations of cow urine in the cultivation of ‘Brasília’ carrots. The treatments consisted of five doses of cow urine (0%, 0.5%, 1.0%, 1.5% and 2.0%) applied during the culture cycle. After 90 days, the agronomic characteristics (weight, length, diameter, productivity, luminosity, chromaticity, and Hue angle) were evaluated. The application of cow urine increased the weight, diameter, and length of ‘Brasilia’ carrots.

Aim: Post-core restorations have been developed to restore and re-functionalize endodontically treated teeth. Today, post-core materials used to show stress distribution similar to a solid tooth are still being researched. This study aimed to compare the von Mises stress (σvm) distributions created by the Zirconium post (ZP), Titanium post (TP), and Glass Fiber post (GFP) materials in the permanent maxillary central incisor using finite element stress analysis (FEA).

Methodology: A permanent maxillary central incisor tooth scanned using microcomputed tomography (µCT) was reconstructed, and a three-dimensional model was created. To these models, ZP, TP, and GFP were applied. Composite resin was modeled as the core structure and ceramic crown as the superstructure. Using FEA, 100 N static force was applied in three directions with vertical (F1-0°), oblique (F2-45°), and horizontal (F3-90°) angles to the models whose restoration was completed. As a result of the applied forces, the stresses on the dentine model (Dm), post model (Pm), and the cement model in between the dentine and the post (Cm) were compared.

Results: The maximum von Mises stress (σvm max) distribution under F1 for Dm was: ZP = 6,07888 MPa, TP = 6,35719 MPa and GFP = 6,81946 MPa. The σvm max distribution under the force F2 for Dm was: ZP = 26,6542 MPa, TP = 27,3694 MPa, and GFP = 28,4495 MPa. The σvm max distribution under the force F3 for Dm was: ZP = 34,7371 MPa, TP = 34,9828 MPa, and GFP = 35,287 MPa.

The σvm max distribution under the force F1 for Pm was: ZP = 17,0361 MPa, TP = 13,1567 MPa, and GFP = 7,85452 MPa. The σvm max distribution under the force F2 for Pm was: ZP = 73,7999 MPa, TP = 52,0089 MPa, and GFP = 25,9903 MPa. The σvm max distribution under the force F3 for Pm was: ZP = 78,8934 MPa, TP = 55,0424 MPa, and GFP = 27,1787 MPa.

The σvm max distribution under the force F1 for Cm was: ZP = 7,95074 MPa, TP = 6,66092 MPa, and GFP = 4,60832 MPa. The σvm max distribution under the force F2 for Cm was: ZP = 16,8296 MPa, TP = 16,8514 MPa, and GFP = 16,526 MPa. The σvm max distribution under the force F3 for Cm was: ZP = 17, 5577 MPa, TP = 16,891 MPa, and GFP = 16,5209 MPa.

Conclusion: In all three forces, the highest σvm max was at ZP, and the least was at GFP. ZP and TP accumulated forces internally rather than transmitting them to the tooth tissue. GFP distributed the forces more homogeneously to the dentine.

Odkud a kam směřuje venkovní výuka? Historie, současnost a trendy ve venkovní výuce v kontextu vzdělávacích teorií
Authors: Nepraš Karel , Šikulová Renata
Published: February 2022

Venkovní formy výuky se v posledních letech v České republice dostá­vají do širšího povědomí pedagogické veřejnosti a jsou s rostoucí měrou využívány v rámci všech úrovní vzdělávání. Postavení české venkovní výuky v této souvislosti zasluhuje zvýšenou pozornost, protože s rostoucím podílem využívání venkovních aktivit se postupně navyšuje i reálný impakt na vzdělávací proces. Venkovní výuka na našich základních školách vychází z tradic vázaných na využívání blízkého okolí školy a školních zahrad a její kořeny sahají do 19. století. V současné době je realizová­na nejčastěji krátkodobě a spíše občasně. Většina škol má k dispozici školní zahradu a alespoň částečně ji pro venkovní formy výuky využívá. Školy mají ve svých kuriku­lárních dokumentech zahrnuty exkurze, vycházky, terénní cvičení, školní výlety, spor­tovní kurzy, případně školy v přírodě, adaptační kurzy a projektovou výuku. Rychle rostoucí vliv na podobu a rozsah venkovní výuky u nás mají v současnosti centra en­vironmentálního vzdělávání, která se zaměřují jak na realizaci konkrétních programů pro školy, tak na vzdělávání a rozvoj pedagogů v daném segmentu a značně přispívají k rozšiřování venkovních forem výuky v českém prostředí. V aktuálně publikovaných metodických dokumentech zaměřených na venkovní výuku majících potenciálně vět­ší dopad na české edukační prostředí je možné identifikovat společné znaky. Konkre­tizovanější podoba venkovní výuky, ke které metodické materiály vedou, v sobě nese prvky otevřené pedagogiky ve smyslu posilování role učitele jako partnera a prů­vodce žáka aktivním učením a zdůrazňuje nutnost aktivní role žáka při edukačním procesu. Charakteristické jsou konstruktivistické rámce a badatelsky orientované přístupy, zdůrazňovány jsou přínosy kooperativního učení a soulad s pedagogikami probouzejícími žákovo uvědomění odpovědnosti za životní prostředí. Aktuální pojetí venkovních forem výuky do značné míry naplňují koncepty holistického pojetí výuky.
Jak učitelé využívají venkovní prostředí pro výuku vzdělávací oblasti Člověk a jeho svět
Authors: Chmelová Štěpánka
Published: February 2022

Hlavním cílem této studie bylo zjistit, jak je aktuálně využívána výuka ve venkovním prostředí učiteli 1. stupně základních škol. Protože učitelé 1. stupně vět­šinou vyučují celou škálu předmětů, pozornost studie byla soustředěna jen na pří­rodovědné předměty – prvouku a přírodovědu. Na této studii participovalo celkem 120 učitelů vyučujících dané předměty na 1. stupni základní školy napříč Českou re­publikou. Jako výzkumný nástroj byl zvolen nestandardizovaný autorský dotazník, který čítal celkem 18 otázek. Studie probíhala v letech 2019 a 2020, a rekognoskuje tak aktuální stav výuky těchto předmětů ve venkovním prostředí. Bylo zjištěno, že 97 % respondentů využívá pravidelně výuku ve venkovním prostředí. Studie byla na­víc doplněna rozhovory s 20 učiteli z praxe, kterým bylo položeno pět otázek k téma­tu výuky ve venkovním prostředí.
Sensemaking unraveled: how teachers process school performance feedback data
Authors: Gutwirth Gila , Goffin Evelyn , Vanhoof Jan
Published: February 2022

The present study investigates how Flemish middle school mathematics teachers make sense of schoolperformanfeedback data from low-stakes, external standardised tests. We take an in-depth look into the interpretive steps they take, based on a conceptual model that integrates intuitive and rational aspects of individual and collective sensemaking and empirical data collected in semi-structured interviews. We describe the nature of these sensemaking processes and consider the impact of influencing factors. Our findings demonstrate that the mere availability of school performance feedback data does not spontaneously spark sensemaking, nor does it necessarily lead to improvements in instructionalpractice. Teachers' sensemaking of schoolperformancefeedback data appears to be a largely intuitive process, grounded in external attributions and absent of triangulation. Challenges regarding expertise and lack of inquiry-based attitude and commitment result in superficial and often incorrect interpretations of the data that tend to remain uncorrected as teachers barely engage in collaborative professional dialogue about the data.

La autonomía de la mujer en relación con el trabajo remunerado
Authors: Uris José María
Published: February 2022

Entre 1960 y 1980 las mujeres se fueron incorporando al trabajo remunerado de forma más numerosa, de hecho, las tasas oficiales de actividad femenina pasaron del 20,1% al inicio de la década de los sesenta al 32,6% en el año 1979, originando un cambio transcendental tanto en el entorno laboral como en el ámbito social. Son múltiples los estudios que se han realizado y se pueden realizar al respecto, el que les presentamos tiene la finalidad de analizar en qué medida la participación de la mujer en el mercado de trabajo ha facilitado su autonomía personal y cómo ha contribuido a que se avanzara en la igualdad de género. El desarrollo del artículo se ha centrado en las circunstancias en que se desenvolvieron las trabajadoras que accedieron a los centros productivos en la década de los sesenta y setenta del siglo anterior, para posteriormente analizar en qué situación se encuentran las mujeres actualmente en el mercado laboral, la discriminación de la que son objeto, a qué limitaciones están sujetas y qué perspectivas les puede deparar la era digital. En fin, cómo pueden afectar todos esos hechos a su carrera profesional y, en consecuencia, a su autonomía personal.
