The purpose of this study was to investigate community perceptions of opportunities for local economic development (LED) in the town of Port St Johns (PSJ), using tourism as a conduit. PSJ is situated at the mouth of the Umzimvubu River along the Wild Coast region in the Eastern Cape of South Africa. A sample of 307 residents of PSJ responded to a questionnaire on the effects of tourism in their community. Overall, the findings reveal a tourism policy gap regarding the LED strategy and implementing a tourism development plan for PSJ. Therefore, the recommendation is to initiate a stakeholder consultative process, culminating in developing a strategic tourism plan for PSJ. This study contributes to the literature on including tourism in the general development plan of communities such as PSJ. At the same time, it provides strategic direction on how community livelihoods can be improved using the natural and cultural resources in PSJ.

Authors: Dhara Souvik
Published: March 2022

Present case study was associated with successful management of a pregnant doe from dystocia by caesarean section. A 1.5 years old pregnant non-descriptive doe was admitted in the TVCC, C.V.A.Sc., Pantnagar, Uttarakhand with a history of complete gestation period and prolonged labor (more than 12 hours). There was protrusion of both fetal forelimbs from the vaginal opening. Gynaecological examination revealed that the fetus was in Nape presentation. The case was diagnosed as dystocia due to abnormal fetal disposition. The animal was subjected to caesarean operation. The operation was performed under light sedation with 0.1 ml of xylazine and regional inverted L- block was also done with 2% Lignocaine. An oblique incision was given at left flank and recovery of one dead male fetus occurred. Post-operative treatment was done with Inj. Amoxicillin-sulbactum @10 mg/kg intramuscularly, Inj. Tribivet® 5 ml intramuscularly, Inj. Chlorpheniramine maleate @0.5 mg/kg intramuscularly, Meloxicum@0.5 mg/kg intramuscularly and NS 250 ml for five days. Local antiseptic dressing and fly repellant spray was advised for every alternative day. The skin suture was removed on 10th day post-surgery

Emergent behavior and neural dynamics in artificial agents tracking turbulent plumes

Published: March 2022

Tracking a turbulent plume to locate its source under variable wind and plume statistics is a complex task; flying insects routinely accomplish such tracking, often over long distances, in pursuit of food or mates. Several aspects of this remarkable behavior and its underlying neural circuitry have been studied experimentally. Here, we take a complementary in silico approach to develop an integrated understanding of behavior and neural computations. Specifically, we train artificial recurrent neural network (RNN) agents using deep reinforcement learning (DRL) to locate the source of simulated turbulent plumes. Interestingly, the agents' emergent behaviors resemble those of flying insects, and the RNNs learn to compute task-relevant variables with distinct dynamic structures in population activity. Our analyses put forward a testable behavioral hypothesis for tracking plumes in changing wind direction, and we provide key intuitions for memory requirements and neural dynamics in turbulent plume tracking.
FAST3D: Flow-Aware Self-Training for 3D Object Detectors
Authors: Fruhwirth-Reisinger Christian , Opitz Michael , Possegger Horst , Bischof Horst
Published: March 2022

In the field of autonomous driving, self-training is widely applied to mitigate distribution shifts in LiDAR-based 3D object detectors. This eliminates the need for expensive, high-quality labels whenever the environment changes (\eg, geographic location, sensor setup, weather condition). State-of-the-art self-training approaches, however, mostly ignore the temporal nature of autonomous driving data. % which contains additional information.To address this issue, we propose a flow-aware self-training method which enables unsupervised domain adaptation for 3D object detectors on continuous LiDAR point clouds. In order to get reliable pseudo-labels, we leverage scene flow to propagate detections through time. In particular, we introduce a flow-based multi-target tracker, that exploits flow consistency to filter and refine resulting tracks. The emerged precise pseudo-labels then serve as a basis for model re-training. Starting with a pre-trained KITTI model, we conduct experiments on the challenging Waymo Open Dataset to demonstrate the effectiveness of our approach. Without any prior target domain knowledge, our results show a significant improvement over the state-of-the-art.
Active Learning for Deep Visual Tracking

Published: March 2022

Convolutional neural networks (CNNs) have been successfully applied to the single target tracking task in recent years. Generally, training a deep CNN model requires numerous labeled training samples, and the number and quality of these samples directly affect the representational capability of the trained model. However, this approach is restrictive in practice, because manually labeling such a large number of training samples is time-consuming and prohibitively expensive. In this paper, we propose an active learning method for deep visual tracking, which selects and annotates the unlabeled samples to train the deep CNNs model. Under the guidance of active learning, the tracker based on the trained deep CNNs model can achieve competitive tracking performance while reducing the labeling cost. More specifically, to ensure the diversity of selected samples, we propose an active learning method based on multi-frame collaboration to select those training samples that should be and need to be annotated. Meanwhile, considering the representativeness of these selected samples, we adopt a nearest neighbor discrimination method based on the average nearest neighbor distance to screen isolated samples and low-quality samples. Therefore, the training samples subset selected based on our method requires only a given budget to maintain the diversity and representativeness of the entire sample set. Furthermore, we adopt a Tversky loss to improve the bounding box estimation of our tracker, which can ensure that the tracker achieves more accurate target states. Extensive experimental results confirm that our active learning-based tracker (ALT) achieves competitive tracking accuracy and speed compared with state-of-the-art trackers on the seven most challenging evaluation benchmarks.
Virtual Reality Intervention Reduces Dietary Footprint: Implications for Environmental Communication in the Metaverse
Authors: Plechatá Adéla , Morton Thomas , Perez-Cueto Federico J.A. , Makransky Guido
Published: March 2022

We developed and tested a Virtual Reality (VR) intervention that allowed users (1) to visualize the consequences of food behavior and (2) to revise their food choices and see how this would alter future climate scenarios. In this pre-registered study, using a 2x2 design, participants experienced intervention with or without normative feedback and via desktop PC or head-mounted display. The intervention advertised online was self-administered by 122 VR users residing in the USA. We observed a moderate-large decline in dietary carbon footprint one week after the intervention regardless of experimental condition (d = -0.63). This change was mediated by increased intentions, self-efficacy, risk perception, and emotional reactions. In addition, normative feedback increased self-efficacy, and changes in response efficacy separately predicted pro-environmental donations. Preliminary findings indicate that psychologically informed VR interventions might promote pro-environmental behavior in VR users and therefore the Metaverse could be a suitable platform for environmental communication.
Market mindset hinders interpersonal trust: The exposure to market relationships makes people trust less through elevated proportional thinking and reduced state empathy
Authors: Kuzminska Anna O. , Gasiorowska Agata , Zaleskiewicz Tomasz
Published: March 2022

In a series of six experiments, we provided evidence that evoking the market mindset negatively affects trust. We found that the market mindset reduces trust compared to the communal mindset (Experiment 1) and compared to a neutral condition (Experiment 2). We excluded alternative explanations by demonstrating that the market mindset negatively affects trust, but not caution or cynicism (Experiment 3). Next, we examined the psychological mechanisms behind the detrimental effect of the market mindset on trust and found that this effect was due to enhanced motivation to use proportional thinking (Experiments 4 and 6) and reduced state empathy (Experiments 5 and 6). Finally, in a preregistered Experiment 6, we showed that these two psychological mechanisms are relatively independent.
Adapting Open Science and Pre-registration to Longitudinal Research
Authors: Petersen Isaac T. , Apfelbaum Keith S , McMurray Bob
Published: March 2022

Open science practices, such as pre-registration and data sharing, increase transparency and may improve the replicability of developmental science. However, developmental science has lagged behind other fields in implementing open science practices. This lag may arise from unique challenges and considerations of longitudinal research. In this paper, preliminary guidelines are provided for adapting open science practices to longitudinal research to facilitate researchers’ use of these practices. The guidelines propose a serial and modular approach to registration that includes an initial pre-registration of the methods and focal hypotheses of the longitudinal study, along with subsequent pre- or co-registered questions, hypotheses, and analysis plans associated with specific papers. Researchers are encouraged to share their research materials and relevant data with associated papers, and to report sufficient information for replicability. In addition, there should be careful consideration about requirements regarding the timing of data sharing, to avoid disincentivizing longitudinal research.
Beliefs and climate change skepticism in French people
Authors: Krause Elise , Weiss Karine , Trémolière Bastien
Published: March 2022

Despite the accumulation of data pointing to climate change and its anthropogenic nature, a part of the population remains skeptical. In the present study, we explored how unwarranted beliefs (e.g., beliefs in paranormal, conspiracy theories) together with beliefs in science predict climate change skepticism. We targeted, in parallel, people’s need for uniqueness, for which recent data suggest an important association with endorsement of conspiracy theories. In a survey conducted with French participants (final N = 477), we observed that endorsement of paranormal beliefs and conspiracy beliefs independently predicts climate change skepticism, beyond and above belief in science, while need for uniqueness was not a predictor. Further analyses showed that conspiracist beliefs partially mediate the relationship between belief in science and climate change skepticism. We discuss these results and the importance for scholars to gain further insights into people’s beliefs and cognition to better grasp the phenomenon.
Emergence and assessment of interpersonal experience and behavior in a nonverbal, generative, game-like paradigm
Authors: Westermann Stefan , Sibilis Arne
Published: March 2022

Dominance, hostility and autonomy are interpersonal phenomena that emerge from the complex dyadic interplay of two individuals reciprocally influencing each other. Assessing the complexity of interpersonal interactions usually involves its reduction, for example with self-report and observer-rated measures informed by the structural analysis of social behavior (SASB). In contrast, letting individuals generate a complex stream of interpersonal experience and behavior from moment to moment is an empirical approach not yet usual in interpersonal theory. In the present study, we developed and evaluated an interpersonal, generative paradigm that allows participants to interact non-verbally and spontaneously with a computer-controlled other player in real-time without the need for introspection or the capacity to verbalize potentially implicit interpersonal processes. In the game-like paradigm, participants use the keyboard to take over objects such as a handcar to move autonomously around and encounter interfering or freedom granting artificial other players. We expected that participants (1) experience the non-verbal so-called game mechanics of the paradigm as interpersonal in nature, (2) behave towards the other players in an interpersonally complementary way, and (3) are influenced by their own trait interpersonal expectations. During the paradigm, 40 participants appraised the majority of the game mechanics and computer-controlled other players as intended. Also, interpersonal traits affected the spontaneous behavior towardsartificial characters. These findings corroborate the feasibility and validity of a generative assessment of interpersonal dynamics beyond self-reports and observer-ratings. The paradigm paves the way for the empirical testing of formal, computational models of dyadic interaction.
The role of personality in neighborhood satisfaction
Authors: Neal Zachary P. , Brutzman Brian
Published: March 2022

Urbanists have long been interested in understanding what makes people satisfied with their neighborhoods. However, relatively little is known about how residents' personality traits may affect their neighborhood satisfaction. In this paper, we explore the direct and indirect associations of personality traits with neighborhood satisfaction in a representative sample of adults in Michigan (USA). We find that each of the personality traits in the five factor model are associated with neighborhood satisfaction in the same way that they are known to be associated with subjective well-being. However, we fail to observe evidence that personality traits moderate the association between perceptions of neighborhoods and neighborhood satisfaction, or that personality's association with neighborhood satisfaction is mediated by neighborhood perceptions. We conclude that there is potential for drawing on theoretical and empirical developments in positive psychology for understanding neighborhood satisfaction, but observe that the underlying mechanisms for the association between personality and neighborhood satisfaction remain unknown.
Validation of the Chinese version of the Psychological Maltreatment Review (PMR): A multidimensional measure of psychological maltreatment
Authors: Xiao Zhuoni , Obsuth Ingrid , Meinck Franziska , Murray Aja Louise
Published: March 2022

The Psychological Maltreatment Review (PMR) is an instrument for retrospectively assessing childhood psychological maltreatment experiences in the dimensions of psychological abuse, psychological neglect, and psychological support; however, it has not yet been validated in Chinese. We recruited 540 Chinese adults and examined: (1) factorial validity and internal consistency, (2) convergent validity, (3) divergent validity, and (4) gender measurement invariance in a Chinese version of the PMR. With minor modifications, model fit for the confirmatory factor model in the overall sample was acceptable and convergent validity was demonstrated. However, model fit for males was poor, which led to the conclusion that gender configural invariance did not hold. Overall, the Chinese version of the PMR appears to produce scores that are valid and reliable for measuring psychological maltreatment in the general population though further work will be required to understand how to measure the concept in a valid and comparable way across genders.

Published: March 2022

Assessment of the corrosion condition of different types of eighty steel-reinforced concrete (SRC) structures of Pokhara Valley (Nepal) was carried out in the present study using a half-cell potential measurement (HCPM) method without destruction of specimens. It is concluded from the experimental results that the SRC structures found at dried places in Pokhara areas showed a low percentage(i.e., < 10%) of corrosion risk, while the fencing pillars used for decoration as well as boundary purposes, and the sewer pipes at damp places found under the high percentage (i.e., > 90%) of corrosion risk. The SRC infrastructures, which have rough and cracked surfaces with high humid surrounding environments, are at high risk of corrosion. The SRC columns of the buildings in Pokhara Valley are at a slightly higher corrosion risk than the SRC roof structures.

Authors: Neupane Nam Raj , Giri Ram Chandra
Published: March 2022

This study aimed to investigate the experiences of teachers of integrated schools in adopting inclusive practices in the classrooms. It was carried out by selecting three integrated schools of two districts, Kathmandu and Kavre, by purposive sampling method. Three teachers from each school were selected by purposive sampling method. The interview guidelines were prepared and got reviewed from a special needs education expert to maintain its reliability, and then administered to the participants. The study found that teachers have been experiencing low self-awareness on teaching students with disabilities. The study also showed a serious lacking in knowledge and skills in teachers and their deviated perceptions towards inclusive practice. Moreover, the study revealed that the school administration can play vital role in developing inclusive culture inside the school and also responsible to provide training to the teachers. Therefore, teachers being the key player in school system, need professional development and exposure to enhance knowledge and skills to handle students with special needs in integrated classrooms.
Barriers to Diversity Management in Classroom: A Case of Rural Community Schools in Nepal
Authors: Sherpa Dawa , Baraily Khagendra
Published: March 2022

This paper attempts to explore and analyse the barriers for diversity management in classroom of a rural community schools in Nepal. Nepal is a multi-ethnic, multi-lingual, and multi-cultural country. As the fabric of society, there is also diversity in the configuration of community schools in rural areas. It entails knowing that each student is unique and acknowledging their uniqueness in the classroom. These might be along the lines of color, ethnicity, gender, sexual orientation, socioeconomic position, age, physical ability, religious views, political convictions, or other ideologies. This paper is mainly based on primary and secondary data. Purposively, head teachers, teachers, and students were selected for interviews. Interviews, field visits, classroom observation, and focus group discussion with teachers and students were conducted, and the data were analyzed thematically based on interview codes. The data shows that they were ignorant of the concept of diversity and how to manage it in the classroom. It is mainly due to the deconstruction of teachers’ attitudes regarding income, professionalism, community structure, physical infrastructure, and socioeconomic discrepancies. This paper suggests managing diversity in the classroom through both policies to integrate curricula and effective management practices in the classrooms. Thus, teachers need pedagogical skills to address the issues of diversity, marginality and oppress groups of the society and barrier of diversity management in the classroom.

Authors: Cahyani Cecylia May , Susanah Susanah
Published: March 2022

Mathematical literacy is an individual’s ability to formulate, employ, and interpret mathematics in various contexts. AKM is one of the government's efforts to measure students' mathematical literacy. This research is a descriptive research with a qualitative approach that aims to describe the profile of students' mathematical literacy in solving AKM in terms of the melancholic, choleric, phlegmatic, and sanguine personality types. The instrument used are personality type questionnaire, mathematical literacy test, and interview guidelines. The results showed that (1) melancholic students wrote complete information, construct mathematical models, used efficient and structured strategies, performed calculations correctly, interpreted and double-checked answers as a whole; (2) choleric students wrote complete information, did not make mathematical models, used structured strategies, performed calculations correctly, interpreted and re-checked answers, but were less careful so the units used were not appropriate; (3) phlegmatic students wrote complete information, construct mathematical models, used quick strategies, interpreted and re-checked calculations, but were less careful so the calculations were not accurate; (4) Sanguine students did not write down known information, did not make mathematical models, used quick strategies, interpreted solutions, but did not re-check answers so  the calculations were inaccurate. Therefore, personality type is one of the factors that cause differences in mathematical literacy.

ANÁLISE DA CO-INTEGRAÇÃO ENTRE A PECUÁRIA DE LEITE E CORTE EM MATO GROSSO
Authors: Michetti Miquéias , Reis Júlio , Kamoi Mariana Yumi Takahashi , Lopes Luciano
Published: March 2022

A pecuária de corte em Mato Grosso é referência nacional, destacando-se entre outros fatores pelo tamanho de seu rebanho. Todavia sua pecuária leiteira vem perdendo participação no cenário doméstico. Invariavelmente, a atividade de corte e leite tem relação intrínseca no estado, onde os ciclos da pecuária de corte são fatores determinantes para explicar a produção e o preço do leite. Isso é observado na presença de uma relação de curto prazo mais intensa entre a produção de leite com seu preço, como esperado, mas também com o preço do bezerro e com o da @ do boi gordo. O efeito da resposta ao impulso na produção de leite mostra que a variável que mais impacta na decisão do produtor em relação à produção de leite é o preço da @ do boi. Choques no preço da @ produzem uma resposta negativa na produção de leite, mas o efeito do preço do bezerro por sua vez, influencia positivamente a produção. A falta de genética especializada pode ser uma das principais causas dessa estreita relação, fazendo com que mudanças no mercado de carne bovina do estado e na produção de carne afetem significativamente a produção e o preço do leite.

Analysis of co-integration between milk dairy and beef cattle in Mato Grosso
 
ABSTRACT: Livestock in Mato Grosso can be considered a national reference, standing out among other factors due to its herd size. However, dairy farming has been losing participation in the domestic scenario. Invariably, beef and milk production have an intrinsic relationship in the state, where beef livestock cycles determine factors to explain the production and price of milk. That is observed in the presence of an intense short-term relationship between milk production and price, as expected, and the calf price and live cattle. The effect of the impulse response on milk production shows that the variable that most impacts the producer's decision concerning milk production are the price of live cattle. Shocks in the price of live cattle produce a negative response in milk production, but the effect of the calf's price in turn positively influences production. The lack of specialized genetics may be one of the main causes of this close relationship, causing changes in the state's beef market and meat production to significantly affect milk production and price.
Key words: livestock; impulse-response; econometrics.

The aim of this paper is to present the impact of discourse social practices on the content of scientific terms. Chosen nomenclature such as: gender (ru. гендер), homosexuality (pl. homoseksualizm;ru. гомосексуализм / гомосексуальность), LGBT (ru. ЛГБТ) is researched. First, the methodological frame is established (discourse analysis), which is followed by a description of Gender Studies and the significance of the researched terms. With this background, it is analyzed how the non-scientific interest in the terms proper for Gender Studies was forming. Subsequently, the main actors of the debates concerning Gender Studies and basic argumentation schemas are pointed out.

Authors: Mahesar Ali Raza , Mahesar Pervaiz Ali , Parveen Sajida
Published: March 2022

The purpose of this research study was to critically analyze the plans of China to develop its economy by connecting itself with the rest of the world through roads network. For this purpose, qualitative research was adopted in which secondary sources were taken. The literature available was thoroughly reviewed, and an interpretive analysis technique was used to analyze and reach a conclusion. The study has concluded that the economic corridor of Central and West Asia has to face a multitude of problems, but these regions are also replete with natural resources. The challenges like infrastructure development and lack of funds could hamper local growth. The study observes that the CCWAEC will promote economic and commercial collaboration and capital flows to these regions and improve regional economic and social development.
Treatment of a symptomatic thalamic pilocytic astrocytoma with reservoir placement and laser interstitial thermal therapy: illustrative case
Authors: Baker Cordell , Crevelt Jordan , Whipple Nicholas , Bollo Robert J. , Cheshier Samuel
Published: March 2022

BACKGROUND

Treatment of pilocytic astrocytomas (PAs) in children can be challenging when they arise in deep midline structures because complete surgical resection may result in significant neurological injury. Laser interstitial thermal therapy (LITT) has provided an alternative treatment modality for lesions that may not be amenable to resection. However, many patients with PAs may be symptomatic from a compressive cyst associated with the PA, and LITT does not obviate the need for cystic decompression in these patients.

OBSERVATIONS

A 12-year-old male presented with left-sided weakness. Magnetic resonance imaging (MRI) revealed an enhancing mass with a large cyst involving the right thalamus and basal ganglia. The patient underwent a reservoir placement for cyst drainage and biopsy of the mass, revealing a pilocytic astrocytoma. He then underwent LITT followed by adjuvant chemotherapy. Sixteen months after LITT, follow-up MRI of the brain revealed no tumor growth.

LESSONS

This is the first case to describe reservoir placement to treat the cystic portion of a pilocytic astrocytoma followed by LITT and targeted chemotherapy. Reservoir placement reduced the cyst’s mass effect and resolved the patient’s symptoms, allowing for treatment options beyond resection.
Atlanto-occipital dislocation in a child: a challenging diagnosis. Illustrative case
Authors: Garvayo Marta , Belouaer Amani , Barges-Coll Juan
Published: March 2022

BACKGROUND

Atlanto-occipital dislocation (AOD) is a highly unstable injury of the osseoligamentous complex at the craniocervical junction that is more common in children. Its diagnosis remains a challenging process that must integrate clinical presentation and radiological criteria.

OBSERVATIONS

A 9-year-old child presented with severe craniocervical trauma (Glasgow Coma Scale score 6) and cardiorespiratory arrest on-site. Prompt resuscitation on-site and transfer to the university hospital were performed, and a computed tomography (CT) scan showed a subarachnoid hemorrhage around the brainstem and a retroclival hematoma. Most of the radiological criteria on CT scans for AOD were negative, except for the occipital condyle–C1 interval, and further imaging with magnetic resonance imaging permitted the diagnosis of AOD with rupture of both the tectorial membrane and the transverse ligament. Occipital-cervical Oc-C1–2 fixation was performed. The neurological outcome was excellent, with full recovery 6 months after the trauma.

LESSONS

AOD should be suspected in all high-intensity trauma in children, especially if the clinical presentation includes cardiorespiratory arrest and other brainstem and/or upper cervical cord symptoms along with premedullary subarachnoid hemorrhage. Understanding the ligamentous nature of the injury resulting in “normal” radiographs or CT scans is important to avoid underdiagnosing AOD, which can have detrimental consequences.
Tangential cranial gunshot wound in an infant in historical context: illustrative case
Authors: Campbell Jeffrey , Piatt Joseph
Published: March 2022

BACKGROUND

Military neurosurgeons have long known that tangential cranial gunshot wounds can be associated with intracranial complications out of proportion to the external appearance of the injury. This phenomenon seems not to have been described in infancy.

OBSERVATIONS

An infant suffered a massive, acute subdural hemorrhage from a contralateral tangential gunshot wound that did not facture the skull.

LESSONS

Similar to adults, infants are subject to catastrophic intracranial injury from gunshots that do not penetrate the skull. The nature of the injury in this case reflected distinctive aspects of the tissue characteristics and proportions of the infant head.
El proyecto muralístico de José Renau en el Casino de la Selva en Cuernavaca, México
Authors:   Instituto Michoacano de Ciencias de la Educación José Mería Morelos, Perez Aguirre Dulze
Published: March 2022

Se analizará el proyecto muralístico que José Renau llevó acabo en el Casino de la Selva por encargo de Manuel Suárez en 1944, el cual consistió en pintar la cantina y el salón de fiestas. El objetivo consiste en rescatar la importancia de esta comisión e identificar los cambios que Renau hizo en España hacia América para dar origen a la versión actual e identificarlo como parte de una propuesta mural que no se concluyó debido a que Renau y Suárez rompieron relaciones. Asimismo, demostrar las aportaciones que dio Renau al muralismo mexicano a través de la escenificación de la conquista de América que contrasta con la visión de Diego Rivera en los murales de Palacio de Hernán Cortes.
