Dick pics and the shifty meanings of porn

ABSTRACT Dick pics are ubiquitous objects in social media shared for the purposes of harassment, flirtation, suggestion, amusement, and titillation alike. Starting with the question of how dick pics are, or are not classifiable as porn, this article opens up lines of inquiry on the possibilities and limitations of porn as a genre marker, content classifier, and reference point in and for understanding sexual content distributed through networked means. In the contemporary moment when sexual content continues to multiply online even as most social media platforms vigilantly moderate and remove it, scholarly vocabularies risk either lagging behind or posing normative categorisation on the things published and shared, from dick pics to webcam shows and OnlyFans content. This article calls for contextual care in how the notion of porn becomes applied to networked sexual media, the shapes of continue to morph, as well as in how dick pics are made sense of as communication devices and cultural symbols.

Anglican Political Theology

This essay develops a constructive account of the ways Anglicans have addressed political questions. The first section outlines the characteristic political rationality of Anglican political theology (APT). This provides a backdrop to a consideration of the relationship between three distinct yet interrelated phenomena—church, nation, and state—and how they were understood as together constituting a polity. The second half situates APT in the context of how Anglicanism, from its origins, is in part a response to processes of modernization, particularly as these emerged in the Atlantic world from the fifteenth century onwards. It then outlines how key concerns of APT emphasize a way of imagining the role of church and nation within history, with providence as an important doctrinal point of reference. The essay closes with some critical reflections on how APT can and should develop going forward.

The pedagogy of action learning facilitation – a critique of the role of the facilitator in an organisational leadership programme

ABSTRACT This paper explores the professional practice of the Action Learning (AL) facilitator through a process of critical inquiry, self-reflection and evaluation of action learning practice within a Higher Education Leadership Programme, commissioned by an English NHS Mental Health Trust. Action research was adopted as the overarching research approach which was built into the one-year post graduate programme. This enabled planning, fact-finding, and taking actions in analysing the role of the AL facilitator as an iterative process to explore the practice of action learning facilitation. It involved examination of the complexities and dynamics within an AL process and how learning and action is facilitated, as well as different relational dimensions that the facilitator must be aware of to effectively manage and support AL set members. Thematic analysis, which involved a 5-step process, was used to collate and investigate the research data. Results from this research reinforce the significance of the role of the AL facilitator in the learning process and offer a framework for pedagogy of AL facilitation presented as the art, craft and apparatus of AL facilitation practice. This framework contributes to the current AL literature by offering a holistic point of reference for the learning and practice of AL facilitation.

The growth mechanism and properties of Bi2212 thin films on miscut substrates by sol-gel method

A sol-gel methodology is employed to prepare Bi2212 thin films on single crystal LaAlO3 miscut substrates with nominal tilt angles of 0°, 5°, 10°, and 15°. The study focuses on examining the phase purity, crystal structure, surface morphology, microstructure, and properties of these thin films. Experimental results indicate that the growth of Bi2212 thin films on miscut substrates proceeds through the step-flow mode using the sol-gel method. Higher tilt angles lead to an increase in the conventional resistivity of Bi2212 thin films. Tilted Bi2212 thin films exhibit a typical transverse Seebeck effect when comparing the resistivity in different directions. Notably, the Seebeck coefficient difference reaches 12 V/K when the substrate tilt angle is set at 15°. Meanwhile, tilted Bi2212 thin films consistently exhibit outstanding superconducting transition temperature (Tc) while demonstrating lower critical current density (Jc) values. These findings offer valuable insights for the development of Bi2212 high temperature superconducting thin films (HTSFs) in thermoelectric and superconductive devices, serving as a reference point for achieving optimal film characteristics.

Hypervolume-Based Cooperative Coevolution with Two Reference Points for Multi-Objective Optimization

An important issue in hypervolume-based evolutionary multi-objective optimization (EMO) algorithms is the specification of a reference point for hypervolume calculation. However, its appropriate specification has not been carefully studied in the literature. Some recent studies have pointed out the importance and difficulty of the reference point specification. Its appropriate specification depends on problem characteristics such as the Pareto front shape and the number of objectives. In this paper, the difficulty of the reference point specification in hypervolume-based EMO algorithms is circumvented by using two reference points. Instead of using only a single reference point, we propose a new hypervolume-based EMO algorithm that can effectively utilize two reference points cooperatively. Experimental results show that the proposed algorithm has good and robust performance on a wide range of test problems. In comparison to hypervolume-based EMO algorithms with only a single reference point, the proposed algorithm can find a wider and more uniformly distributed solution set. On a recently proposed real-world problem suite, the proposed algorithm shows competitive performance in comparison to state-of-the-art algorithms.

ATM-R: An Adaptive Tradeoff Model With Reference Points for Constrained Multiobjective Evolutionary Optimization.

The goal of constrained multiobjective evolutionary optimization is to obtain a set of well-converged and well-distributed feasible solutions. To achieve this goal, a delicate tradeoff must be struck among feasibility, diversity, and convergence. However, balancing these three elements simultaneously through a single tradeoff model is nontrivial, mainly because the significance of each element varies in different evolutionary phases. As an alternative approach, we adapt distinct tradeoff models in various phases and introduce a novel algorithm named adaptive tradeoff model with reference points (ATM-R). In the infeasible phase, ATM-R takes the tradeoff between diversity and feasibility into account, aiming to move the population toward feasible regions from diverse search directions. In the semi-feasible phase, ATM-R promotes the transition from "the tradeoff between feasibility and diversity" to "the tradeoff between diversity and convergence." This transition is instrumental in discovering an adequate number of feasible regions and accelerating the search for feasible Pareto optima in succession. In the feasible phase, ATM-R places an emphasis on balancing diversity and convergence to obtain a set of feasible solutions that are both well-converged and well-distributed. It is worth noting that the merits of reference points are leveraged in ATM-R to accomplish these tradeoff models. Also, in ATM-R, a multiphase mating selection strategy is developed to generate promising solutions beneficial to different evolutionary phases. Systemic experiments on a diverse set of benchmark test functions and real-world problems demonstrate that ATM-R is effective. When compared to eight state-of-the-art constrained multiobjective optimization evolutionary algorithms, ATM-R consistently demonstrates its competitive performance.

Risks for animal health related to the presence of ergot alkaloids in feed.

The European Commission requested EFSA to provide an update of the 2012 Scientific Opinion of the Panel on Contaminants in the Food Chain (CONTAM) on the risks for animal health related to the presence of ergot alkaloids (EAs) in feed. EAs are produced by several fungi of the Claviceps and Epichloë genera. This Opinion focussed on the 14 EAs produced by C. purpurea (ergocristine, ergotamine, ergocornine, α- and β-ergocryptine, ergometrine, ergosine and their corresponding 'inine' epimers). Effects observed with EAs from C. africana (mainly dihydroergosine) and Epichloë (ergovaline/-inine) were also evaluated. There is limited information on toxicokinetics in food and non-food producing animals. However, transfer from feed to food of animal origin is negligible. The major effects of EAs are related to vasoconstriction and are exaggerated during extreme temperatures. In addition, EAs cause a decrease in prolactin, resulting in a reduced milk production. Based on the sum of the EAs, the Panel considered the following as Reference Points (RPs) in complete feed for adverse animal health effects: for pigs and piglets 0.6 mg/kg, for chickens for fattening and hens 2.1 and 3.7 mg/kg, respectively, for ducks 0.2 mg/kg, bovines 0.1 mg/kg and sheep 0.3 mg/kg. A total of 19,023 analytical results on EAs (only from C. purpurea) in feed materials and compound feeds were available for the exposure assessment (1580 samples). Dietary exposure was assessed using two feeding scenarios (model diets and compound feeds). Risk characterisation was done for the animals for which an RP could be identified. The CONTAM Panel considers that, based on exposure from model diets, the presence of EAs in feed raises a health concern in piglets, pigs for fattening, sows and bovines, while for chickens for fattening, laying hens, ducks, ovines and caprines, the health concern related to EAs in feed is low.

Da prática de campo da tradição naturalista da Biologia à aula de campo na escola: distanciamentos e aproximações

Abstract This study has a theoretical and, to some extent, essayistic nature, as it embarks on an investigative and reflective journey that deviates from traditional methodological constraints. The goal is to encourage dialogue between the traditional naturalistic field practices and the field-based lessons in biology education. We use the field practices of traveling naturalists from the sixteenth century as a point of reference, aiming to establish an interpretive time horizon for contemporary field classes. By investigating the attributes and progression of field scientific practices, we can assess their impact on biology field courses and how they differ from them based on the specific circumstances. Making connections between science and teaching can help to break away from the daily grind of pedagogical routines and facilitate the necessary reevaluation of biology field lessons.

Socioeconomic structure of yellow corn producers in two Mexican municipalities as reference sources

Yellow corn has gained strategic importance for the current government of Mexico due to the enormous amount of thisgrain that is imported, which in turn represents a large flight of capital due to the costs paid abroad to purchase it. Underthese premises, work is being done to obtain a characterization of the different productive units of yellow corn in theirsocioeconomic structure, which allows the generation of an intervention protocol at the three levels of government, in thosemunicipalities where it is possible to plant yellow corn, with native seeds and agroecological fertilizers. The purpose is topromote the development of rural culture, in every sense, and at the same time represents greater income for producers dueto the monetary resource that will no longer go abroad and will remain in the production units. To achieve these objectives,a municipality that has planted yellow corn for several years is taken as a reference point: Ocuituco, Morelos. And anothermunicipality that planted corn in large areas and stopped doing so: Calpulalpan, Tlaxcala.

A Combination Model of Shifting Joint Angle Changes With 3D-Deep Convolutional Neural Network to Recognize Human Activity.

Research in the field of human activity recognition is very interesting due to its potential for various applications such as in the field of medical rehabilitation. The need to advance its development has become increasingly necessary to enable efficient detection and response to a wide range of movements. Current recognition methods rely on calculating changes in joint distance to classify activity patterns. Therefore, a different approach is required to identify the direction of movement to distinguish activities exhibiting similar joint distance changes but differing motion directions, such as sitting and standing. The research conducted in this study focused on determining the direction of movement using an innovative joint angle shift approach. By analyzing the joint angle shift value between specific joints and reference points in the sequence of activity frames, the research enabled the detection of variations in activity direction. The joint angle shift method was combined with a Deep Convolutional Neural Network (DCNN) model to classify 3D datasets encompassing spatial-temporal information from RGB-D video image data. Model performance was evaluated using the confusion matrix. The results show that the model successfully classified nine activities in the Florence 3D Actions dataset, including sitting and standing, obtaining an accuracy of (96.72 ± 0.83)%. In addition, to evaluate its robustness, this model was tested on the UTKinect Action3D dataset, obtaining an accuracy of 97.44%, proving that state-of-the-art performance has been achieved.

Cooperation with dynamic asymmetric evaluation in complex networks from a risk perspective.

The choice of strategy exposes individuals to the risk of betrayal. This induces individuals' irrational tendencies in strategy selection, which further influences the emergence of cooperative behavior. However, the underlying mechanisms connecting risk perception and the emergence of cooperation are still not fully understood. To address this, the classic evolutionary game model on complex networks is extended. We depict the interaction between strategy imitation and payoff evaluation from two perspectives: dynamic adjustment and irrational assessment. Specifically, the probability distortion involved in the dynamic selection of imitative reference points, as well as the asymmetric psychological utility associated with reference point dependence, is emphasized. Monte Carlo simulations demonstrate that individual irrational cognition induced by the risk of strategy selection can promote the emergence of cooperative behavior. Among them, the risk sensitivity within psychological utility has the most significant moderating effect. Moreover, the promoting effect of strong heterogeneity and high clustering in the network topology on cooperation under risk scenarios has been clarified. Additionally, the influence of initial states on the emergence of cooperation follows a step-like pattern. This research offers valuable insights for further exploring the cooperation mechanisms among irrational agents, even in scenarios involving the regulation of group cooperation behavior in risky situations.

Update of the risk assessment of inorganic arsenic in food.

The European Commission asked EFSA to update its 2009 risk assessment on arsenic in food carrying out a hazard assessment of inorganic arsenic (iAs) and using the revised exposure assessment issued by EFSA in 2021. Epidemiological studies show that the chronic intake of iAs via diet and/or drinking water is associated with increased risk of several adverse outcomes including cancers of the skin, bladder and lung. The CONTAM Panel used the benchmark dose lower confidence limit based on a benchmark response (BMR) of 5% (relative increase of the background incidence after adjustment for confounders, BMDL05) of 0.06 μg iAs/kg bw per day obtained from a study on skin cancer as a Reference Point (RP). Inorganic As is a genotoxic carcinogen with additional epigenetic effects and the CONTAM Panel applied a margin of exposure (MOE) approach for the risk characterisation. In adults, the MOEs are low (range between 2 and 0.4 for mean consumers and between 0.9 and 0.2 at the 95th percentile exposure, respectively) and as such raise a health concern despite the uncertainties.

Mapping of fundus photography to 3D imaging for ocular radiotherapy

Aims/Purpose: Ocular Proton Therapy (OPT) is one of the main treatments for uveal melanoma. Full inclusion of fundus images in the treatment planning is currently hindered by the refraction of the eye's optical elements. In this study we developed and evaluated a method to correct for these effects, with the final aim of enabling an OPT‐planning which spares more of the healthy retina.Methods: A paraxial method to correct for the scaling fundus photographs of the central retina was developed using ray transform matrices. This method was subsequently extended to the full retina using ray tracing simulations in Zemax OpticStudio through the ZOSPy library [1]. These methods were evaluated in 33 eyes in which the corneal topography, lens location, thickness and curvature, and retinal shape were personalized. The resulting scaling of the fundus images was finally compared with the method currently used in OPT planning (EYEPLAN).Results: For the central retina the magnification relative to the average eye ranged from 0.79 to 1.50 and was approximately inversely proportional to the eye's spherical equivalent. For the peripheral retina, a nodal point‐based mapping provided no systematic errors and the least variation between subjects (up to 2.5 degrees at 70degrees eccentricity). This method proved a significant improvement compared to the currently used method which had a systematic error of approximately 21 degrees as it incorrectly modelled the refractive effect of the eye's optics.Conclusions: Using the nodal point as a reference point, fundus images can be accurately mapped to 3D imaging, enabling the inclusion of optical information in OPT planning.

From catering for death rituals to establishing a restaurant – the journey of KSN Iyengar Catering Service

Learning outcomes The learning outcomes of this case study are to develop an understanding of informal business practices (IBP) from an economic and a behavioural perspective, identify the pros and cons of IBP and how they can hinder the realization of entrepreneurial aspirations, use the effectuation perspective to understand the entrepreneurial journey of the protagonist and apply the strengths, weaknesses, opportunities and threats (SWOT) analysis and effectuation theory to understand the need for transition from informal to formal business practices. Case overview/synopsis KSN Iyengar Catering Services (KSNICS) had gained popularity for cooking and serving traditional “Iyengar” cuisine during festivals, ceremonies and other auspicious occasions. With the passage of time, KSNICS slowly diversified into offering food carrier services, corporate catering and preparation of sweets/savouries during the Diwali festival. The enterprise managed to sustain itself without additional investments from external sources. KSNICS was managed in an informal manner by the protagonist, Krishna Kumar. After almost 30 years of KSNICS’s existence, in 2021, Kumar felt that they should diversify into the restaurant business by establishing an authentic “Iyengar” restaurant. In spite of the unpredictable market and the challenging times due to the COVID-19 pandemic, he had somehow managed to sustain his catering business. However, given the informal methods through which he operated his catering services and in the post-COVID-19 pandemic scenario, would it be prudent on his part to establish a restaurant? Complexity academic level This case study is suitable for post-graduate- and executive-level instruction in courses such as managerial skills, entrepreneurship and human resource management. In managerial skills course, it can be used for applying SWOT analysis from a particular perspective for effective decision-making. In entrepreneurship-related courses, it can be used to introduce aspects such as entrepreneurship orientation, effectuation and decision-making. In organizational behaviour and HR-related courses, it can be used to highlight how employees can be trained and motivated and how businesses can be sustained within the scale, especially during challenging times. Irrespective of the course, the IBP discussion would remain a constant point of reference because that was the context under which the current business was operating.

Cultural Interpretation as a Theological Task in Northeast India

Recently, there have been attempts to develop contextual (tribal) Bible reading. While giving priority to these efforts, there appears to be neglect for the cultural interpretation of tribal communities in Northeast India. In light of this reality, as an exegete, I would argue that there is a need to learn to interpret culture to relevantly interpret and translate the text in each context/society. As a case in point of cultural interpretation, an attempt will be made to read the presence and emergence of the Tangkhul confessing community as a text analogue and also as a point of reference for reading-interpreting culture.

Determination of mercury in soil and water from a gold mining area in Karang Jaya Sub-district, Musi Rawas Utara, Indonesia

The present study focuses on the assessment of Hg distribution in both soil and water samples from the small-scale gold mining region of Karang Jaya Sub-district, Musi Rawas Utara Regency, South Sumatra Province. For over 30 years, this region has witnessed persistent utilization of mercury as an amalgam for gold extraction. The investigation encompasses an analysis of total mercury levels in soil samples obtained from Sukamenang, Muara Batang Empu, and Terusan Villages. As a comparative reference point devoid of gold mining activities, the neighboring Muara Lakitan Village was selected. The obtained results indicate a moderate to strong contamination level across the 30 sampled locations based on the Geoaccumulation Index (Igeo), with an average Igeo value of 2.6. Furthermore, Pollution Load Index (PLI) and Contamination Factor (CF) values demonstrate high contamination. Conversely, analysis of river water samples from 30 stations along the Rupit River reveals that most of the samples comply with quality standards (<0.0005 mg/L), with an average value at 0.000322 mg/L; only four stations exhibit total Hg concentrations surpassing regulatory thresholds. All soil and river water samples from the control area (10 stations) exhibited no signs of pollution. Appropriate investments in technology, finance, and technical skills are needed to reduce mercury pollution due to small-scale gold mining activities.

Institutional investor ESG activism and exploratory green innovation: Unpacking the heterogeneous responses of family firms across intergenerational contexts

This paper investigates the heterogeneous responses to institutional investor ESG activism by expanding reference point theory among non-family firms and family firms with different intergenerational contexts. Using a Chinese family firm database comprising 14,425 observations from 2012 to 2020, this study finds that institutional investor ESG activism is more likely to stimulate exploratory green innovation in family firms than in non-family firms. Such linkage between institutional investor ESG activism and exploratory green innovation is stronger in second-generation family firms than in first-generation firms. Furthermore, this study explores the moderating roles of family involvement and financial slack in first- and second-generation family firms as they respond to institutional investor ESG activism. Specifically, both family involvement and financial slack can enhance the positive impact of institutional investor ESG activism on exploratory green innovation in the context of second-generation family firms. The moderating effect of family involvement is not significant, whereas the moderating effect of financial slack turns into be negative in the context of first-generation family firms. Our study highlights the heterogeneous responses to institutional investor ESG activism of family firms with different intergenerational contexts.
