In step with rapid advancements in computer vision, vehicle classification demonstrates a considerable potential to reshape intelligent transportation systems. In the last couple of decades, image processing and pattern recognition-based vehicle classification systems have been used to improve the effectiveness of automated highway toll collection and traffic monitoring systems. However, these methods are trained on limited handcrafted features extracted from small datasets, which do not cater the real-time road traffic conditions. Deep learning-based classification systems have been proposed to incorporate the (...) above-mentioned issues in traditional methods. However, convolutional neural networks require piles of data including noise, weather, and illumination factors to ensure robustness in real-time applications. Moreover, there is no generalized dataset available to validate the efficacy of vehicle classification systems. To overcome these issues, we propose a convolutional neural network-based vehicle classification system to improve robustness of vehicle classification in real-time applications. We present a vehicle dataset comprising of 10,000 images categorized into six-common vehicle classes considering adverse illuminous conditions to achieve robustness in real-time vehicle classification systems. Initially, pretrained AlexNet, GoogleNet, Inception-v3, VGG, and ResNet are fine-tuned on self-constructed vehicle dataset to evaluate their performance in terms of accuracy and convergence. Based on better performance, ResNet architecture is further improved by adding a new classification block in the network. To ensure generalization, we fine-tuned the network on the public VeRi dataset containing 50,000 images, which have been categorized into six vehicle classes. Finally, a comparison study has been carried out between the proposed and existing vehicle classification methods to evaluate the effectiveness of the proposed vehicle classification system. Consequently, our proposed system achieved 99.68%, 99.65%, and 99.56% accuracy, precision, and F1-score on our self-constructed dataset. (shrink)

The coastal zone of Bangladesh is endowed with dynamic ‘Terrestrial’ and ‘Coastal and Marine ecosystem’. The zone confronts with declined environmental quality owing to unethical anthropogenic interventions. Few studies regarding ethical attitudes of local communities to conserve the coast were conducted earlier. Two objectives, such as (i) heavy metal concentration, and (ii) physio-chemical quality of sample soil and water were selected to reveal the environmental state of study area. Five heavy metals like- Cadmium, Copper, Iron, Lead, and Zinc; and four (...) physio-chemical parameters such as, the pH, Electrical Conductivity, Temperature, and Turbidity of sample soil and water were measured. The average concentration of Pb in soil is 10 times higher than world average (0.03 mg/g), while Cd concentration in soil is two times more than world average (0.11 mg/L). The concentration of Fe at Inani beach water is 1.54 mg/g more than world average (3.4 mg/g). The physio-chemical parameters are within standard range. Unethical discharge of toxic effluents from shrimp hatcheries, and municipal garbage are main sources of pollution, which ensue into environmental degradations. Concentration of five heavy metals and Calcium Carbonate (CaCO3) in sample mollusk shells exhibit biodiversity deterioration. The mollusk shells from Inani beach contains 0.04 mg/L Cd,0.08 mg/L Cu, 0.42 mg/L Fe, 0.38 mg/L Pb, and 0.07 mg/L Zn. The CaCO3 content in mollusk shells at Inani beach is 49.5%, which indicates the degradation of the mollusks, as shells normally are made with 95% - 97% Calcium Carbonate. Hence, the Department of Environment (DOE), Bangladesh (GoB) declared the area as an ‘Ecologically Critical Area’ (ECA). The concerned stakeholders, like- CPP volunteers and officials, Forest Division, Fisheries Research Institute, Bangladesh Water Development Board, Union Chairman and Journalists of Cox’s Bazar recommended insertion of moral values among local stakeholders through trainings, motivational lectures, demonstrations and dramas, as well as, incorporation of lessons about consequences of unethical activities upon geo-environment into text books. Though least practice has been found regarding moral values during survey, the present research advocates in developing ‘Knowledge pool’ about coastal environment, creating awareness, and developing moral ethics among the local, regional and national stakeholders.

The debate in acknowledging street harassment as an existing social problem renders research necessary on the topic. Street harassment is said to occur when it takes place in a public setting and is initiated by a stranger. Through this correlation research, we aimed to establish the relationship between experiencing street harassment and fear of victimization. A positive correlation between the experience of street harassment and fear of victimization was hypothesized and a positive correlation between street harassment and negative reaction to (...) harassment was also hypothesized. Additionally, the most recurring type of public harassing behaviors was identified as well. Two self report questionnaires were administered; A gender based harassment scale assessing the frequency of 8 harassing behaviors which ranged on a likert scale from 0 to 4 and a modified version of The Fear of Crime survey measuring fear of victimization. These questionnaires were administered to a sample of 250 females recruited via convenient sampling technique that had experienced street harassment previously. Percentages, mode and Pearson’s Product correlation were used to statistically analyze data. Results showed a significant, weak positive correlation between street harassment and fear of victimization and a moderate positive correlation between experiencing street harassment and negative reaction towards harassment. The most frequent harassing behavior was being stared in a manner that made the victims uncomfortable with 98% of participants experiencing it, followed by 83.5% of the participants experiencing non-verbal sounds. Through this research, we were able to conclude street harassment does have negative implications for women. (shrink)

The purpose of this research is to examine the influence of servant leadership on teachers of moral education degree programs in Pakistan. By utilizing social learning, we propose that servant leadership and perceived coworker support can reduce the knowledge hiding by enhancing the sense of organization-based psychological ownership. The findings of time-lagged and multi-source data indicate that servant leadership has a negative relationship with knowledge hiding. Our results also indicate that psychological ownership mediates the effects of servant leadership on knowledge (...) hiding. Moreover, a higher level of perceived coworker support enhances the sense of psychological ownership which helps to reduce knowledge hiding. This research extends strong support for the proposition that servant leaders who adopt an employee-centered management approach, stressing personal integrity and care for employees significantly affect employee attitudes and behaviors. Moreover, this study suggests that managers should demonstrate care toward their subordinates which helps them to reduce negative behaviors. (shrink)

Hardy is the last of the Victorian and one of the most popular novelists of England. He, being an author of unique endowments, was not much esteemed in his life time. Hardy became the victim of stereotypical criticism and was badly ostracized by the ecclesiastical circles and the critics of his time as they merely focused on the depressing features of his fiction. This paper intends to reveal certain aspects of his work which remained neglected for a long time. The (...) present study is designed to focus on those characteristics of his work which win the title of a modern novelist for him. Hardy was quite conscious of the shifting environment around him at the vogue of industrialization that left profound marks on his meditative temperament. His depiction of the 19th century scenario is dominated with clash and collision between innovation and tradition. His art deals with twofold aspects of modernity exposing the sanguine and gloomy consequences of modernity. Owing to such an approach of the writer he is regarded as a social realist and one of the earliest of the modern novelists. Hardy poignantly observes the pathetic condition of the labourers, on one hand, and the modern mechanical advancements, one the other, which were of little benefit for the common man in society. The current study is designed to focus upon his approach to the modern developments in the broad context of social and political changes. Hardy is a modern novelist as he concentrates on the current issues such as gender, class, social and psychological disorders, etc. He is a supporter of class and female liberation. (shrink)

Excessive use of social media is a developing concern in the twenty-first century. This issue needs to be addressed before it has any more significant consequences than what we are currently experiencing. As a preventive technique, advertisements and awareness-raising campaigns about the detrimental impact of digital technologies are used. The application of novel mathematical techniques and terminologies in this field of study will have significant potential to enhance healthy living by preventing certain ailments. This is the most compelling justification for (...) conducting a new study with the most up-to-date techniques at our disposal. This study investigates clear and concise transmission in order to generate a deterministic mathematical model of social media addiction S M A using the fractal-fractional derivative operator. Also, the analysis of the S M A model in terms of the invariant domain, the existence of a positive invariant solution, and equilibria assumptions are stated in a detailed manner. Besides that, the basic reproduction number ℝ 0 < 1 is computed, demonstrating that the proposed methodology is more efficacious. The Atangana-Baleanu FF differential operators are recently defined in FF differential operators that are applied to characterize the S M A model’s mathematical algorithm. We investigated the numerical behaviour of the S M A in three ways: changing the fractional-order α as well as the fractal-dimension ℘ ; changing α while keeping ℘ constant; and changing ℘ while keeping α constant. Our examined visualizations and simulation studies using MATLAB for the numerical modelling of the aforementioned system showed that the novel developed Atangana-Baleanu FF differential operators produce remarkable results when compared to the classical frame.

In this article, we investigated a deterministic model of pneumonia-meningitis coinfection. Employing the Atangana–Baleanu fractional derivative operator in the Caputo framework, we analyze a seven-component approach based on ordinary differential equations. Furthermore, the invariant domain, disease-free as well as endemic equilibria, and the validity of the model’s potential results are all investigated. According to controller design evaluation and modelling, the modulation technique devised is effective in diminishing the proportion of incidences in various compartments. A fundamental reproducing value is generated by (...) exploiting the next generation matrix to assess the properties of the equilibrium. The system’s reliability is further evaluated. Sensitivity analysis is used to classify the impact of each component on the spread or prevention of illness. Using simulation studies, the impacts of providing therapy have been determined. Additionally, modelling the appropriate configuration demonstrated that lowering the fractional order from 1 necessitates a rapid initiation of the specified control technique at the largest intensity achievable and retaining it for the bulk of the pandemic’s duration.

Recent discussions have fixated on the distinction between perception and cognition. How should recognition be understood in light of this distinction? The relevant sense of recognition involves a sensitivity to particulars from one's past. Recognizing the face of a familiar friend is one instance of this phenomenon, as is recognizing an object or place that one has viewed before. In this article, I argue that recognition is an interface capacity that straddles the border between perception and cognition.

This study focuses on determining the number of children considered ideal by Pakistani husbands and identifying the factors associated with this, with a special emphasis on family type. A cross-sectional survey was conducted among married males residing in four areas of Khairpur district. An equal number of study participants were selected systematically from each field site to achieve the required sample size of 500. Interviews were conducted by trained fieldworkers using a structured questionnaire to obtain information on background socioeconomic characteristics, (...) family structure and reproductive health knowledge and practices, in particular family planning. Multivariate logistic regression analyses were used to assess the hypothesis that family type has an independent association with husbands opinions regarding ideal number of children can help strengthen population control efforts in Pakistan.

For statistical evaluation t-test was applied, which specified that male university students experience more disturbed eating attitudes compare to female learners. This clears that distressed eating attempts are not limited to females, but is now affecting males as well. Thus to avert its budding prevalence, teaching institutions should supervise its amassed risks in their students and stimulate them to healthy lines of eating. (shrink)

Publication date: 30 August 2017 Source: Author: Ghulam Abid, Tahira Hassan Butt Employees are the building blocks and valuable assets in an organization. Organizational researchers and practitioners have shown a burgeoning attention to satisfy and retain key performer as the cost of leaving a job is very high for the employing organizations. Discovering turnover intention in its formation stages is very crucial, not only to resist its’ piled up effect but also to control the actual turnover in the future. (...) Most of the times, management is not aware of the employee’s quit intention because employees don’t show their intention explicitly until they actually leave the organization. However, majority of the times employees share their feeling with their colleagues or other close work mates. Based on positive relationship at work, we argued that the individuals who work together normally share their feelings with their close colleagues regarding their decision of leaving or staying with the current employer. Therefore, the objective of the current study is to investigate the relationship between turnover intention and expressed turnover intention. Furthermore, we offer a new perspective to data collection from other sources, which will assist us in shortening the questionnaire, also minimizing the common method bias and knowing the quit intention from other source. Finally, theoretical and practical implications along with direction for future studies are also discussed. (shrink)

Three recent publications on BEND3 firmly establish its role as a novel sequence‐specific transcription factor that is essential for PRC2 recruitment and maintenance of pluripotency.

This paper is intended to elaborate the anthropocentric paradigm in the study of Islamic law which is done for two reasons. The first is the increasing trend of theocentricism within various puritan communities. This trend rejects the contextualization of Islamic law and has the potential to produce radical movements in the name of religion. The second is that, Islamic law studies is still rarely associated with the issues of legal paradigms, even though they are considered as the foundation in the (...) establishment of Islamic law. Thus, this paper is written as an attempt to make the prophetic social science paradigma an analytical tool for puritans’ Islamic law epistemology. This study reveals that the epistemological demystification is very important for the study of contemporary Islamic law. There are two steps in carrying out epistemological demystification: the first is the transformation of the basic structure of Islamic law. This transformation requires a shifting issue from theocentric to the anthropocentrism. The transformative theoanthropocentric paradigm as the basic legal structure has the capability to contextualize Islamic law which is not only relevant to the Muslim community, but also to the community as a whole. The second is the development of a theoretical framework. Concerning with this, Kuntowijoyo offers analytic-synthetic theories which accommodate a demystified vision as a link to a transformative theological foundation. (shrink)

Suddenly, COVID-19 has changed the world and the way people work. Companies had to accelerate something they knew was imminent in the future, but not immediate and extremely humongous. This situation poses a huge challenge for companies to survive and thrive in this complex business environment and for employees, who must adapt to this new way of working. An effective e-leadership, which promotes companies’ adaptability, is needed. This study investigates the existing knowledge on teleworking and e-leadership; and analyzes the supposed (...) challenges. The literature review shows that companies with effective e-leadership can view teleworking as an opportunity. It is advantageous for not only companies’ productivity but also the environment and people who work remotely. However, a traditional or no leadership can result in some risks. Thriving in remote work environments implies that managers must adjust the companies’ structure, making them less hierarchical, and developing new abilities to establish a strong and trustworthy relationship with their employees to maintain their competitiveness, while retaining a genuine concern for their employees’ well-being. Similarly, successful e-leadership must be able to consolidate and lead effective virtual teams to accomplish organizational goals.

Patients’ perception with regards to their use in medical teaching is an under-researched area in Pakistan. The objective of this qualitative, pilot study was to determine the perspectives of hospital admitted patients on their being used in the medical education of students in a private medical institution. An attempt to understand the dynamics of interactions between patients, students and doctors was also made and to see how this affected the doctor-patient relationship. A qualitative study with in-depth interviews was conducted in (...) a private medical college of Islamabad, Pakistan with a total of 20 adult patients. The focus was on their experiences with bedside teaching. This pilot study reveals interesting findings about patient-physician interactions in Pakistan. Patients had a traditionally passive role in medical education putting more onuses on the doctor to impart knowledge to the medical students. Patients comforted themselves in the knowledge that they were following Allah’s command when they were involved in the teaching of medical students. The apparent altruism of Pakistani patients in this study was influenced mainly by religious reasons, following the commandments of Allah to help develop future healers for humanity. The culture evident in the medical college where this study was conducted is reflective of the social power ladders that pervade Pakistani society. The positions of doctors and medical teachers in Pakistani society are hardly challenged to debate. Little attention has been paid to the values that influence the cultural and social frameworks within which Pakistani medical teachers, medical students and the patients function. (shrink)

Young adult literature has been studied to understand how authors represent characters who denotes their version of experiencing mental disability or social distress. Thus the following thematic analysis of young adult novels points a question, that whether portrayal of mental disability/social distress is empowering or not. Certainly, mental disabilities seem to be different in novels: in their attempts to represent mental disability/social distress as a real experience, they’re sometimes also attached to popular conceptions of protagonist’s love-affair. Hence, to focus on (...) novels representing mental disability/social distress; themes are hypothesized to explore the identity of the protagonist, society’s influence on protagonist and whether novel romanticize or represents realistic portrayal of disability/distress. Six novels have been selected-One memory of Flora Banks, Everything-Everything, All the Bright Places, 13 Reasons Why, When we Collided and Will Grayson, Will Grayson. These novels calls attention towards how society aggravates disability and shun those who don’t meet certain expectations to be mentally healthy. Literature is a powerful social force and conversation starter about disability/distress awareness to address and deal with challenges. Thus it’s important to recognize that it plays a key role in the empowerment and appreciation for disability which has been the center of this analysis. (shrink)

Engaging communities in community-based health research is increasingly being adopted in low- and middle-income countries. The use of community advisory boards is one method of practicing community involvement in health research. To date, few studies provide in-depth accounts of the strategies that CAB members use to practice community engagement. We assessed the perspectives, experiences and practices of the first local CAB in Eswatini, which was implemented as part of the MaxART Early Access to ART for All study. Trained Swazi research (...) assistants conducted two focus group discussions and 13 semi-structured interviews with CAB members who had been part of the MaxART study for at least 2.5 years. Interviews explored CAB composition and recruitment, the activities of CAB members, the mechanisms used to engage with communities and the challenges they faced in their role. The MaxART CAB played an active role in the implementation of the Early Access to Art for All study, and activities mainly focused on: promoting ethical conduct, in particular privacy, consent and confidentiality; communication and education, communicating about the study and educating the community on the benefits of HIV testing and early access to HIV treatment; and liaising between the community and the research team. Strategies for interacting with communities were varied and included attending general community meetings, visiting health facilities and visiting public places such as cattle dipping tanks, buses, bars and churches. Differences in the approach to community engagement between CAB members living in the study areas and those residing outside were identified. The experiences of the first CAB in Eswatini demonstrate that community engagement using CABs is a valuable mechanism for engaging communities in implementation studies. Considerations that could impact CAB functioning include clearly defining the scope of the CAB, addressing issues of CAB independence, the CAB budget, providing emotional support for CAB members, and providing continuous training and capacity building. These issues should be addressed during the early stages of CAB formation in order to optimize functioning. (shrink)

This study examines the conditions under which apologies help to elicit forgiveness and restore trust following trust violations between leaders and followers. The intentionality and severity of violations are examined in a critical incident study and a laboratory study. The results support a model in which forgiveness mediates the relation of apology quality and trust. More importantly, the moderation–mediation model shows that apology quality influenced forgiveness and subsequent trust following violations that were moderate in severity–intentionality combination. The effect of apologizing (...) affects trust directly without forgiveness when the severity–intentionality combination held minor or extreme intensity. The results suggest a range in which apologies are effective and enrich understanding of the conditions under which trust can be recovered through an apology–forgiveness process in leader–follower relationships. The contribution of the study lies in elucidating that the combination of severity and intentionality of leaders’ trust violations has greater importance than either one separately. (shrink)

© 2015 Elsevier Inc.Toxoplasma gondii is a protozoan pathogen in the phylum Apicomplexa that resides within an intracellular parasitophorous vacuole that is selectively permeable to small molecules through unidentified mechanisms. We have identified GRA17 as a Toxoplasma-secreted protein that localizes to the parasitophorous vacuole membrane and mediates passive transport of small molecules across the PVM. GRA17 is related to the putative Plasmodium translocon protein EXP2 and conserved across PV-residing Apicomplexa. The PVs of GRA17-deficient parasites have aberrant morphology, reduced permeability to (...) small molecules, and structural instability. GRA17-deficient parasites proliferate slowly and are avirulent in mice. These GRA17-deficient phenotypes are rescued by complementation with Plasmodium EXP2. GRA17 functions synergistically with a related protein, GRA23. Exogenous expression of GRA17 or GRA23 alters the membrane conductance properties of Xenopus oocytes in a manner consistent with a large non-selective pore. Thus, GRA17 and GRA23 provide a molecular basis for PVM permeability and nutrient access. (shrink)

This is the first empirical study that not only examines the influence of all three dimensions of online retailers’ post-sale services on customers’ online shopping perceptions and decisions, but also considers differences between male and female customers. Finally, this research provides theoretical and managerial implications based on conceptual and empirical evidence. (shrink)

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

In his paper, “Higher‐order truths about chmess,” Daniel Dennett argues that “[m]any projects in contemporary philosophy are artifactual puzzles of no abiding significance.” In other words, much contemporary academic philosophy is a waste of time. In this chapter, we use mathematics, models, and metaphysics, to expand and clarify Dennett's chmess analogy. We further the argument that some contemporary academic philosophy loses its way and chases chmess‐like endeavors – arguing that philosophy is bloated by extraneous, esoteric, and bizarre philosophical projects that (...) aren't detached from reality but only related to it tangentially. Chmess‐like games, like some contemporary academic philosophy, nick reality and then shoot off on their own trajectory, often down intellectual rabbit holes. (shrink)
