Recognizing Human-Object Interactions in Videos

Understanding human actions that involve interacting with objects is very important due to the wide range of real-world applications, such as security surveillance and healthcare. In this thesis, three different approaches are presented for addressing the problem of human-object interactions (HOIs) recognition in videos. Firstly, we propose a hierarchical framework for analyzing human-object interactions in a video sequence. The framework comprises Long Short-Term Memory (LSTM) networks that capture human motion and temporal object information independently. These pieces of information are then combined through a bilinear layer and fed into a global deep LSTM to learn high-level information about HOIs. To concentrate on the key components of human and object temporal information, the proposed approach incorporates an attention mechanism into LSTMs. Secondly, we aim to achieve a holistic understanding of human-object interactions (HOIs) by exploiting both their local and global contexts through knowledge distillation. The local context graphs are used to learn the relationship between humans and objects at the frame level by capturing their co-occurrence at a specific time step. On the other hand, the global relation graph is constructed based on the video-level of human and object interactions, identifying their long-term relations throughout a video sequence. We investigate how knowledge from these context graphs can be distilled to their counterparts to improve HOI recognition. Lastly, we propose the Spatio-Temporal Interaction Transformer-based (STIT) network to reason about spatio-temporal changes of humans and objects. Specifically, the spatial transformers learn the local context of humans and objects at specific frame times. The temporal transformer then learns the relations at a higher level between spatial context representations at different time steps, capturing long-term dependencies across frames. We further investigate multiple hierarchy designs for learning human interactions. The effectiveness of each of the proposed methods mentioned above is evaluated using various video action datasets that include human-object interactions, such as Charades, CAD-120, and Something-Something V1

THE EFFECTS OF MANAGERIAL CONSULTATION ON VOICE FUTILITY WITH ORGANIZATIONAL JUSTICE AS MODERATOR: MEDIATING ROLE OF PSYCHOLOGICAL SAFETY

Managerial consultation is the precursor in encouraging employee voice behaviors. In present day, voice is regarded as an essential tool in improving the performance of any organization. Employee voice acts as a driving factor in influencing organizational change and suggesting innovative ideas. Organizational justice moderates the relationship between managerial consultation and voice futility. Psychological safety motivates employees to feel safe in voicing their opinions. When employees feel they will not be treated unjustly and are free to express their ideas, they are more likely to voice their opinions without hindrance. Moreover, by anticipating positive responses from the manager, employees are more likely to have trust in management to appreciate their input. This study has three propositions. The first states that managerial consultation has a positive impact on voice futility. Secondly, organizational justice moderates this relationship while lastly, psychological safety mediates this relationship. The study concludes in the acceptance of these propositions. Researchers should explore the psychological factors of managers regarding employee voice

The Impact Of Change-Oriented Leadership On Voice Behavior And Intent To Quit With Employee Personality As Moderator And Perceived Issue Threat As Mediator

Change-oriented leadership is a specific leadership style in encouraging employee voice behaviors. In present day, voice is regarded as an essential tool in improving the performance of any organization. Employee voice acts as a driving factor in influencing organizational change and suggesting innovative ideas. Employee personality moderates the relationship between change-oriented leadership and perceived issue threat. When employees feel they will not be treated unjustly and are free to express their ideas, they are more likely to voice their opinions without hindrance. Moreover, by anticipating positive responses from the manager, employees are more likely to have trust in management to appreciate their input; hence managerial openness is a positive indicator of voice behaviors and intent to quit. This study has four propositions. The first states that transformational leadership has a positive impact on voice behaviors and intent to quit. Secondly, managerial openness has a positive impact on voice behaviors and intent to quit. Thirdly, employee personality moderates this relationship while lastly; perceived issue threat mediates this relationship. The study concludes in the acceptance of these propositions. Researchers should explore the diversity factors associated with change-oriented leadership and voice behaviors

THE IMPACT OF MANAGERIAL CONSULTATION ON VOICE FUTILITY AND INTENT TO QUIT WITH TRANSFORMATIONAL LEADERSHIPAS MODERATOR: A MEDIATING ROLE OF FELT OBLIGATION TOWARDS CONSTRUCTIVE CHANGE

Employee voice is essential to the constructive progress of any organization. While many organizations have adapted to the culture of more open communication, some are still lagging behind in providing employees with the power to speak up to their supervisors. The barrier has led to general job employees’ dissatisfaction frequently resulting in employee’s intent to quit. Managerial consultation is, hence, essential to avoid such situations while a more supportive leadership provides employees with the motivation and inspiration they require to feel obliged to bring about positive change in their organizations. This study has proposed four hypotheses based on managerial consultation, voice futility, and intent to quit while transformational leadership and feeling obliged towards constructive change have been used as the moderator and mediator, respectively. The study concludes that there exists positive relationship between managerial consultation, voice futility, and intent to quit, provided that effective managerial consultation reduces the intent to quit and vice versa

Descriptive study of the species Limnophora Robineau-Desvoidy 1830 (Diptera:Muscidae) in Iraq – Kerbala

The current study was conducted during the year 2020 in some areas of the holy Kerbala governorate with the aim of diagnosing some species of insects of environmental and biological importance and knowing their distribution and the time of occurrence during seasons. The results showed that the species Limnophora obsignata (Rondani, 1866) (Muscidae: Coenosiinae) was recorded for the first time in Iraq. It was found that throughout the study period, this species was more frequently found in river habitats and seasons with moderate temperatures and humidity (spring and autumn). The external appearance of this species was described, as well as the anatomy of the male reproductive system of the samples

The Predictive Ability of the Self-Esteem scale Dimensions for Bully Victimization Among Basic School Students in the City of Ma'an, Jordan

The study aimed at identifying the ability of the self-esteem scale dimensions in predicting bully victimization among basic school students in the city of Ma'an in Jordan.  The study examined the variations in students’ levels of self-esteem and levels of bully victimization in relevance to gender, academic achievement, and birth order. The bully victimization scale and self- esteem scale were used to achieve the purposes of this study. The sample included 225 students (104 males and 121females) from grades 6 to 9. The results showed statistically significant negative relation between total self-esteem scale and its dimensions and the levels of bully victimization and that the dimensions of self-esteem scale explained 17.5 % of variance of the degree of bully victimization. It was also revealed that family and social dimensions of self-esteem were statistically significant in predicting levels of bully victimization among the participants. Furthermore, there were statistically significant differences in students’ levels of self-esteem scale in favor of males and students with “excellent” academic achievement. However, there were no statistically significant differences in the students’ levels of self-esteem related to birth order. Finally, female students reported significantly higher levels of bully victimization; and that academic performance and birth order were not statistically significant.

Demographic, Clinical, and Biomedical Profile of Diabetic Patients Receiving Home Healthcare in Saudi Arabia

Background: Identifying characteristics of diabetic patients receiving home healthcare will help in designing services that respond to their conditions and improve their health status and quality of life. The aim of this study was to describe the demographic, clinical, and biomedical characteristics of diabetic patients receiving HHC. Methods and Results: We used a descriptive cross-sectional design, and data were collected from 251 medical records of diabetic patients in two home healthcare centers in Saudi Arabia. The collected data included demographic, clinical, and biomedical profile variables. The average age was 74.7±11.6 years, with most patients (93.2%) aged 60 or older. The most common treatment modality was multiple daily insulin injections with or without oral medication (38.6%), followed by oral medication with sulfonylurea (19.9%). Pressure injury was the most reported complication/comorbidity, affecting 33.1% of patients. Cerebrovascular disease came next, affecting 20.7% of patients, followed by cardiovascular disease, ischemic heart disease, and nephropathy, affecting 12.3%, 10%, and 6.4% of patients, respectively. Only 4.2% of patients experienced hypoglycemia, and only 5.6% of patients were hospitalized due to DM complications. The mean HbA1c was 7.6±1.7%, with approximately 71.7% of the diabetic patients having HbA1c8% (P<0.0001). The median (range) LDL was 2.93 (1-317) mmol/L. The median (range) eGFR was 76.6 (9-389) mL/min/1.73m2. Around 48% of the population had an eGFR<60 mL/min/1.73m2. Conclusion: Our findings show satisfactory glycemic control, acceptable LDL levels, low incidence of hypoglycemia, and minimal hospital admissions

Do People Live at Sea Level and the Dead Sea Level Have Different Patterns of Anti-Hypertensive Drugs

Background: people live at various areas of sea level may have different patterns of anti-hypertensive drugs. Such a relation has never been reported in Jordan. Study objectives: the current study investigated how the sea level will impact the prevalence of hypertension in these areas, and how will affect the pharmacological properties of such a population. Methodology: a cross-sectional study design was involved to collect data from study participants. A total of 1000 participants were randomly selected from the two study areas. 500 participants from each. Participants were matched for age and gender. Blood pressure were measured for all participants. Blood samples were withdrawn to investigate the level of angiotensin II. Data was collected through organizing a working excel sheet and was further analyzed through using SPSS version 20. Data was presented as means, standard deviations, frequencies and percentages. The relationships between variables were examined using independent T-test. Significance was measured at an alpha &lt; 0.05. Study findings: the main findings of the present study were that the mean of SBP is significantly higher in the Dead Sea (122.42±10.53 mmHg) than the Sea level area (118.07±11.64 mmHg), (p=0.001). Another significant variable was MBP which its mean was 91.64 ± 8.90 mmHg in the Dead Sea and 89.84 ± 8.72 mm Hg. The difference in the mean was statistically significant (p=0.001). The level of angiotensin II was 8.84 ± 4.65pg/ml in the Dead Sea area and 11.21± 6.05pg/ml in the area of the Sea level. The difference in the mean of the two study areas was not statistically significant (p&gt;0.05). Conclusions: although the level of angiotensin II was not significantly varied between the study areas, but its trend was to be higher in the Sea level area. It was surprised to have higher levels of SBP and MBP in the Dead Sea rather than the Seal level area. It can be implied that the therapeutic options of hypertensive drugs follow different patterns independent of angiotensin II pathways
