Objective: To evaluate the association of blood and semen lead with male infertility. Design: It was a case control study carried out in the department of Biochemistry, BSMMU, from January, 2004 to December, 2004.Subjects: Of 52 male subjects, 26 were infertile with oligospermia and / or asthenospermia. Age matched 26 normospermic subjects with normal standard semen parameters (volume, count, motility and morphology) were selected as controls. None had the history of occupational exposure to lead.Results: Median values of blood lead were 19.96 µg/dl and 17.68 µg/dl (normal <25 µg/dl); semen lead were 29.56µg/dl and 28.17 µg/dl (normal 15.37 ± 3.92 µg/dl) in cases and controls respectively. Neither blood lead nor semen lead showed significant difference between cases and controls. There was significant positive correlation between blood lead and semen lead concentrations. There was no significant correlation of semen and blood lead concentrations with other semen parameters & serum hormone concentrations (FSH, LH, & Testosterone) in cases. Conclusion: Though the association of blood or semen lead with male infertility was not established in our study, yet, increased seminal lead concentration found in our study subjects may be indicative of subtle exposure of lead in our environment. So, further study with larger sample size is needed. The clinicians should consider the lead measurements when evaluating male partners of couples with unexplained infertility and for assessment of lead status, semen lead measurement can be recommended.DOI: http://dx.doi.org/10.3329/pulse.v4i1.6955Pulse Vol.4 January 2010 p.10-13

Forty rats, in groups of ten, were orally dosed with corn oil, corn oil and 2,000 mg/kg trichloroethylene (TCE), corn oil and 2,000 mg/kg lead carbonate, or a mixture of 2,000 mg/kg each TCE and lead carbonate, in an effort to determine whether or not dual administration of both TCE and lead would have an additive effect on neurotoxicity and overall health as indicated by behavioral and physiologic measurements and tissue pathology. A functional observational test battery (FOB) was performed before, during, and after dose administration to assess dose-related changes. The FOB testing assessed behavioral and physiologic measurements such as gait, open field activity, posture, grip strength, and handling reactivity. Pathological examination included assessing dosing related changes in the testis, spleen, heart, liver, kidney-adrenals, and brain. Results indicated that each compound was toxic individually, and that the combination of the two neurotoxicants provided conflicting indications of both reduced and additive toxicity. The toxicity of lead carbonate caused the vast majority of toxic consequences in the study. A reduction in body weight and an increased resistance to cage removal were the only statistically significant changes observed in the FOB that were due to concurrent administration of lead and TCE. Organ-to-body weight and organ-to-brain weight calculations showed evidence of a statistical difference between the lead and lead/TCE dosed animals for liver, kidney-adrenals, and body weight. The significance of these changes is not fully understood.

Rationale: Lead-exposure during developmental periods may alter reinforcing patterns of drugs of abuse in adulthood. Anxiety related mechanisms may also influence drug intake. Interactions between the two altering factors may exist. Objectives: The present study examined the effects of perinatal lead-exposure on cocaine self-administration after a GABAA antagonist pre-treatment. Methods: Female rats were exposed to a regimen of 16 mg lead daily for 30 days prior to breeding with un-exposed males. This continued throughout gestation and lactation until postnatal day (PND) 21. On PND 63, animals were implanted with indwelling jugular catheters. After a 7 day recovery period, animals were trained to self-administer 0.50 mg/kg cocaine intravenously [IV]. After stable responding had been established, testing procedures began using combinations of 0.03 and 0.06 mg/kg cocaine [IV] and 0.00, 0.50, 1.00 and 2.00 mg/kg bicuculline (a GABAA antagonist) intraperitoneal [IP]. Results: Bicuculline pre-treatment caused directionally opposite effects in both treatment groups (Group 0-Lead and Group 16-Lead) at the 0.06 mg/kg cocaine dose. Group 0-Lead animals showed an increase in self-administration, while Group 16-Lead animals showed a decrease in responding on the active (cocaine) lever. Results at the 0.03 mg/kg cocaine dose showed no discernable pattern. Group 0-Lead animals decreased in active lever responding at the 2.00 mg/kg bicuculline dose. Group 16-Lead animals showed no differences in responding at any dose of bicuculline. Conclusions: These data further suggest the influential role of GABA in mediating cocaine reward and the ability of developmental lead-exposure to alter mechanisms mediating drug responsiveness even after exposure has terminated.

Male nurses are but a small percentage of the total nurse population in the United States, and most certainly have potential to increase in numbers if the profession appeared more attractive as a career option for men. The purpose of this research was to discover the decision factors used by males that led them to enroll in Associate Degree nursing programs in Illinois community colleges. To set the background and context, the study explored the history of community colleges and that of nursing. Included was nursing as a profession, nursing in the United States, the country’s impending nursing shortage and the role of men in nursing.

Using a qualitative case study method of design, the study adapted a multi-theoretical framework encompassing gender theory (GT) and career developmental theory (CDT). These theories were further broken down by discussing, in particular, Holland’s Theory (HT) of Personality and Vocational Choice and Krumboltz’s Social Learning Theory (KSLT) under CDT. Nine first year male ADN students from three separate Illinois community colleges were individually interviewed. Findings discovered that the first year male students experienced a distinctive decision making process with eight emerging themes revealing the males’ decision making about their ADN enrollment process.

As a result of the study’s findings, MURSE: Resurreccion’s Male Nursing Student Decision Making Pyramid model was developed to elaborate the steps of how males make decisions about their ADN enrollment. An understanding of these factors can provide opportunities for community colleges, and perhaps universities, to improve recruitment and retention of males in nursing programs. A result would be increased numbers of males enrolling in Associate as well as Baccalaureate nursing programs. Such knowledge held by colleges may help to address a manpower solution to the impending worldwide nursing shortage.

The majority of studies have demonstrated a right hemisphere (RH) advantage for the perception of emotions. Other studies have found that the involvement of each hemisphere is valence specific, with the RH better at perceiving negative emotions and the LH better at perceiving positive emotions [Reuter-Lorenz, P., & Davidson, R.J. (1981) Differential contributions of the 2 cerebral hemispheres to the perception of happy and sad faces.Neuropsychologia, 19, 609¿613]. To account for valence laterality effects in emotion perception we propose an `expectancy¿ hypothesis which suggests that valence effects are obtained when the top-down expectancy to perceive an emotion outweighs the strength of bottom-up perceptual information enabling the discrimination of an emotion. A dichotic listening task was used to examine alternative explanations of valence effects in emotion perception. Emotional sentences (spoken in a happy or sad tone of voice), and morphed-happy and morphed-sad sentences (which blended a neutral version of the sentence with the pitch of the emotion sentence) were paired with neutral versions of each sentence and presented dichotically. A control condition was also used, consisting of two identical neutral sentences presented dichotically, with one channel arriving before the other by 7 ms. In support of the RH hypothesis there was a left ear advantage for the perception of sad and happy emotional sentences. However, morphed sentences showed no ear advantage, suggesting that the RH is specialised for the perception of genuine emotions and that a laterality effect may be a useful tool for the detection of fake emotion. Finally, for the control condition we obtained an interaction between the expected emotion and the effect of ear lead. Participants tended to select the ear that received the sentence first, when they expected a `sad¿ sentence, but not when they expected a `happy¿ sentence. The results are discussed in relation to the different theoretical explanations of valence laterality effects in emotion perception.

ENGLISH ABSTRACT: Introduction-The golf swing is a complex, sequenced movement of body segments. This movement is smooth and well timed and is referred to as the kinematic golf sequence. This kinematic sequence illustrates the rotational speed, which occurs between the upper and lower body segments. Hip rotation plays an integral part to a sound kinematic sequence by providing a pivotal point between the upper and lower body segments, ensuring a synchronised golf swing. Hip rotation kinematics during a golf swing has received relatively little attention compared to other body segments’ movements. However, clinicians need to have a clear understanding of the rotational contribution that each hip make during golf swing in order to enhance the athlete’s performance and reduce the risk of injury. The aim of this descriptive research project was to obtain and investigate the total passive and total dynamic rotation range of movement in both the lead and trail hips of healthy, young adult, male golfers. Methodology-Seven, low handicapped, male golfers between the ages of 18 and 40 years were randomly selected in the Western Cape region from areas surrounding Stellenbosch University’s Tygerberg campus. A questionnaire gathered participant demographics that determined participatory eligibility. A preliminary reliability study established a baseline measurement for passive total articular hip rotation. Seatadjusted total passive hip rotation ranges of motion (ROM) measurements were collected with a hand-held inclinometer. Dynamic total hip rotation kinematic data was captured during a golf swing with an 8-camera video analysis system (VICON). Data analyses were performed with Statistica version 10. Hand-held inclinometer intra-rater reliability was determined with a two-way interclass correlation, standard error of measurement and a 95% confidence interval level. A Spearman correlation coefficient determined correlation between the total passive and total dynamic rotation range of movement in both the lead and trail hips. Results-Passive intra-rater reliability was reported as 0.81 (95% CI: 0.46-0.96). The total average passive articular range between the lead (62.1° ±6.4°) and trail hip (61.4° ±3.8°) did not report any significant difference (p=0.8). The total average dynamic golf swing articular range between the lead (29° ± 6.5°) and trail hip (35.° ±7.8°), was reported as significantly (p=0.04) asymmetric. The findings also demonstrated a positive correlation between the passive and dynamic total articular range in a lead hip, whereas a negative correlation was reported in a trail hip. During the golf swing the lead hip utilised 46.4%(± 8) of the total passive available hip rotation, whereas the trail hip utilised 58.8% (±13.2). Discussion and Conclusions-The findings of this study show that, the passive rotation ROM in a hip (LH=62°; TH=61°) of a golf player does not exceed the available range it has during a golf swing. The golfer’s hip utilises 46% of the available passive range of movement in the lead hip and 59% in the trail hip. In the clinical field careful consideration should be given to the motivation behind mobilizing, treating or stretching the hips of a golf player. These findings can be incorporated in future research on the relationship between hip-rotation ROM and reduction in the incidence of injuries amongst golfers.
AFRIKAANSE OPSOMMING: Inleiding-Die gholfswaai is n komplekse, opeenvolgende beweging van verskeie liggaamsegmente. Hierdie gladde opeenvolgende bewegings word die kinematiese gholfpatron genoem. Hierdie kinematiese opeenvolgende bewegings bied ’n illustrastrasie van die rotasiespoed waarteen die beweging tussen die boonste en onderste liggaamsegmente plaasvind. Heuprotasie speel ’n deurslaggewende rol in hierdie glad verlopende kinematiese proses. Dit dien as ’n spilpunt tussend die boonste en onderste kwadrant, wat op sy beurt weer ’n gesinkroniseerde gholfswaai verseker. Die heuprotasie kinamtieka tydens n gholfswaai het relatief minder aandag ontvang in vergelyking met ander liggaamsegmente. Klinici moet instaat gestel word om ’n duidelike begrip aangaande die bydrae wat heuprotasie tydens ’n golfswaai lewer, te ontwikkel. Die atleet se prestasie kan sodoende verbeter word, en die risiko tot beserings kan ook sodoende voorkom word. Die doel van hierdie beskrywende navorsingsprojek was om te bepaal wat die totale passiewe en die totale dinamies rotasie omvang van die leidende en volgende heupe van gesonde jong mans wat gholf speel, te ondersoek. Metodologie-Sewe gholf-geskoolde manlike gholf spelers met ’n lae voorgee en tussen die ouderdom van 18 en 40 jaar is ewekansig gekies. Hierdie kandidate is gekies uit die omliggende gebiede van die Stellenbosch Tygerberg kampus in die Wes-Kaap waar hulle relatief naby woonagtig was. ’n Vraelys is aangewend om demografiese eienskappe van elke deelnemer in te samel. Hierdie inligting wat deur die vraelys bekom is, is gebruik om te bepaal of die deelnemers in aanmerking is vir die studie. ’n Voorlopige, intra-meter betroubaarheidstudie is gedoen vir passiewe, totale artikulêre heuprotasiemetings wat met ’n hand hanteerbare hoek meter geneem is. ’n Algemene fisiese ondersoek is in die biomeganiese labaratorium afgehandel om te bepaal of die deelnemers geskik is vir die toetse. Sit-aangepaste passiewe totale hip rotasie beweging metings was ingesamel met 'n hand hanteerbare hoek meter. Intra-meter betroubaarheid is bepaal met ’n twee-rigting interklas korrelasie, standaard foutmeting en ’n 95% vertroue interval vlak. Dinamiese totale heup kinematiese rotasiedata is afgeneem met ’n hoë-spoed 3-D videografiestelsel (VICON) tydens 'n gholfswaai. Data-ontleding is bereken met ’n Statistica weergawe 10. Die gemiddelde en Spearman korrelasie koëffisiënt is gebruik as aanwysers van verspreiding. Resultate-Passiewe inter-meter betroubaarheid word geraporteer as 0.81 (95% KI: 0.46-0.96). Die resultate dui op ’n onbeduidende totale passiewe artikulêre reeks verskille tussen die leidende (voorste) (62.1 ± 6.4 °) en volgende (agterste) heupe (61.4 ° ± 3.8 °). ’n Beduidende totale dinamiese artikulêre reeks van die leidende (29 ° ± 6.5 °) en volgende heupe (35.9 ° ± 7.8 °) is tydens die gholfswaai bereik. Verdere resultate toon ’n positiewe korrelasie tussen die passiewe en dinamiese totale artikulêre reeks in die leidende heup, terwyl ’n negatiewe korrelasie gerapporteer word vir die volgende (agterste) heup. Tydens ’n gholfswaai gebruik die leidende heup 46.4% (± 8%) van die totale passiewe beskikbaar heuprotasie, terwyl die opvolgende (agterste) heup 58.8% (± 13.2%) aanwend. Bespreking en gevolgtrekking-Die bevindinge van hierdie studie toon dat tydens ’n gholfswaai, ’n gesonde gholfspeler nie die beskikbare passiewe beweging wat in sy heup bestaan oorskry nie. Slegs 46.4% van die beskikbare passiewe beweging in sy leidende heup word gebruik, en 58.8% van sy agterste heup. Die klinisie moet deeglike oorweging gegee word aan die motivering agter die mobilisering, strekke en die behandeling van die heupe van ’n gholfspeler. Hierdie bevindings kan in toekomstige navorsing geimplimenteer word om die verhouding wat tussen die omvange vand heuprotasie bestaan te ondersoek. Die voorkoming van moontlike toekomstige beserings in gholfspelers kan ook verhoed word.

Dissertação para obtenção do Grau de Mestre em Conservação e Restauro
This project involved the conservation of a 19th century portrait in oils from the Ecomuseu do Seixal (Portugal). The painting of “João Luiz Lourenço” was in very poor condition. Because of the range and severity of the problems presented, it offered an opportunity to explore important aspects of painting conservation in-depth. The approach to its treatment required an empirical investigation of a number of materials and techniques used in the field of conservation/restoration. Of additional interest, the painting exhibits widespread evidence of metal soap (lead carboxylate) aggregates protruding through the paint from the ground layer. The painting’s materials and the metal soaps aggregates were studied and characterised with different analytical techniques: μ-EDXRF (Energy Dispersive X-ray Fluorescence), μ-Raman Spectroscopy, μ-FTIR (Fourier Transform Infrared Spectroscopy) and SEM-EDX (Electron Scanning Microscopy with Energy Dispersive X-ray Spectroscopy). Part 1: describes the study of the materials and the technique of the painting, and of the metal-soap aggregation within the painting’s ground layer. Observation with the Optical Microscope and with SEM-EDX of paint/ground cross-sections reveals the presence of two visually distinct lead carboxylate aggregates: one, completely white, and the other with a white centre surrounded by distinct red particles identified as red lead (minium: Pb3O4) by μ-Raman. The presence of these two types raises questions about whether there are different starting materials for the aggregates or whether they could be in different states of evolution. Part 2: describes the design and implementation of the conservation/restoration treatment. The treatment of the painting raised challenges and at various stages involved the exploration of non-traditional methods. At every stage during the treatment the consequences of an intervention was carefully considered in relation to the subsequent steps. All decisions were taken according to the painting’s intrinsic conservation problems and materials and with regard to the future environment of the painting.

Violence has been declared a public health problem by the World Health Organisation (1996). Violence prevention strategies are actively used in efforts to rehabilitate offenders during their incarceration, and are intended to prepare them for reintegration into society and to prevent recidivism. Given the lack of research undertaken on violence prevention strategies in the gang-ridden context of Cape Town, South Africa, this dissertation looks at a prison intervention programme, Help I am Free, that uses performance arts as a case study to investigate the potential impacts of such intervention strategies. The paper does so by outlining the experiences of five male gang members before, during, and after their time in prison. Using a cross-sectional qualitative research design, the dissertation explores participants’ life histories and seeks to shed light on the ways in (and degrees to) which such programmes may influence the men’s attitudes towards themselves and others, and the likelihood of their successful reintegration into society. The theoretical frameworks used draw on applied theatre theories, social-cognitive theories, and theories of masculinities. The paper argues that programmes such as Help I am Free may impact participants’ perceptions of self and others strongly, and may also lead to an increased sense of self-worth and motivation to change lifestyle. However, it also indicates the limitations of the programme to achieve sustained success, given the structural barriers which afflict South Africa. The paper outlines a number of challenges that the men face while on parole, and concludes that while prison intervention programmes, and art programmes specifically, may trigger a sense of healing and encourage more positive notions of self, there are more comprehensive strategies in post-release urgently needed in order to prevent recidivism and to achieve authentic social re-integration.

This Master’s thesis has been carried out within the subject area of Production Development and Management and aims to reduce internal lead times in make-to-order (MTO) and job-shop production environments with the use of identified theoretical methods. The reason this particular production environment was chosen was the flexibility and satisfaction it provides its customers. Today, customers expect customised products, a situation which causes problems for manufacturers as they are unable to produce such products in large amounts. In order to investigate problems with these kinds of environments and the causes for long lead times, we have conducted a literature study where we identified the problems these particular kinds of production environments experience regarding production planning and control which are related to the immense amount of time consumed by changeovers because of high demand variance and high requirements for customisation. To affirm the theoretical findings, we opted to undertake a case study and chose Talent Plastics Gislaved AB as our case, because this company utilises an MTO and job-shop production environment for its production of highly customised products with high demand variance. In the analysis of our case, we found that the wastes in the organisation were similar to those identified in the theoretical findings. The current planning system and the current state of the manufacturing lead time system were evaluated and a theoretical framework using a combination of lean production, work load control and constant work-in-process theories was suggested. We claim that concentrating on the reduction of setup times can lead the job-shop towards drastically decreased lead times and a much more effective use of time throughout the organisation. Because the organisation will continue to face problems due to the ever-increasing demand variance and requirements for customisation, there are plenty of opportunities for further research in these kinds of production environments. Emerging theories, such as quick response manufacturing, may also be tested to construct an efficient framework.

Resumo:

Sugar maple trees were fertilized in June 1988 on an individual tree basis in an attempt to improve tree vigour. Fertilizers included K$ sb2$SO$ sb4$, a phosphate and base cations mix, and a commercial organic mix (Maplegro). No effect of fertilization was found on foliar nutrient concentrations and water status of trees during the 1990 growing season. This is possibly the result of dilution in tree biomass, the addition of non limiting nutrients or the experimental design. A positive effect of fertilization on growth was found for one site and, at another, fertilization was found to impair growth. Thus fertilization requirements of declining sugar maple are site specific. Soil Mg was higher around trees fertilized with Maplegro, and trees fertilized with K$ sb2$SO$ sb4$ had low leaf buffering capacities.

AbstractIncreasing diversity in organizations has been shown to lead to more open, innovative and productive organizations. Within sustainability science, the need for diverse opinions, experiences and disciplines cannot be overstated. Two of the core principles of sustainability are normative and collaborative competencies that emphasize the need for diverse stakeholder involvement. To solve complicated, societal problems, we need to ensure that voices typically unheard, have a part to play in developing solutions for sustainability challenges. This is becoming even more critical as we see the impacts of sustainability problems being disproportionately felt by vulnerable populations, which often are populated by Black, Indigenous, People of Color (BIPOC). Despite this evident need, our current academic positions in the field of sustainability and environmental science, like most STEM disciplines, are predominantly held by white, male faculty.

In this short chapter I revisit the role that male investment might play in the evolution of male mate choice. Simply put, one might expect with more male investment into reproduction, they may be more selective about with whom they mate. If the male investment is larger than the female investment sex roles are expected to flip. This is, however, not common. But even if males almost never invest as much or more than females, in many species they do invest somewhat, or even heavily. Should this lead to choosiness in males? I will provide a few examples where choosiness may be linked to investment in males.

Thelma & Louise is a landmark feminist film that became an iconic symbol of women who take control of their own lives. The picture, Callie Khouri’s first screenplay, won an Academy Award. The two lead characters are off on an adventure when a rapist changes their lives. For most of the movie they are wanted for murder and chased by the police. The in-depth performances by Susan Sarandon and Geena Davis show rare insight into the female perspective. This motion picture was shot on location and has a controversial ending that still fascinates and puzzles viewers. Scott, British born, visually captures the roads and vistas of America in a way that supports this unusual and powerful story.

Spermatozoan production is tightly controlled by the multistep process of spermatogenesis and spermiogenesis. Physiological and molecular disruption in spermatogenesis can lead to various reproductive disorders including male infertility. Male infertility is associated with various etiologies, but mechanism is not determined yet. MicroRNAs (miRNAs) are almost 22 nucleotides long, non-protein coding RNA that play an essential role in posttranscriptional regulations in various biological processes including spermatogenesis. The current review is aimed to summarize the recent literature on the role of miRNAs in male infertility and spermatogenesis and their potential in diagnosis, prognosis, and therapy of the disease. miRNAs have shown tremendous potential to be used as diagnostic and prognostic marker and therapeutic target in diseases related to male infertility. Experimental evidence reveals that aberrant expression of miRNAs affects different cell types and different stages of spermatogenesis, which ultimately leads to male infertility. To exploit the full potential of miRNAs, characterization of unidentified miRNAs is required to understand the miRNA-mediated regulatory mechanism related to male infertility.

The aerostatic lead screw is a non-contact type lead screw in which the contact surface of a male screw and a female screw is supported by a pressurized air film. It is characterized by the features that: (1) there is no degradation in accuracy due to friction wear; (2) no environmental pollution is caused by a leak and scattering of lubrication fluid; and (3) maintenance is easy and simple. However, drawbacks are that vibration is liable to occur and therefore the static rigidity is low. The aerostatic lead screw is useful for semiconductor fabrication and also effective in positioning a table on which a sample is placed in a biomicroscope. This study relates to a drunkenness analysis of the aerostatic lead screw. The drunkenness of a contact-type lead screw represented by the ball screw is generally transferred directly from the male screw to the female screw. In the aerostatic lead screw, the drunkenness based on machining accuracy error of each screw flank is not directly transferred onto the female screw and is instead averaged out by balancing of load capacities among each screw flank, so that the enhanced accuracy in positioning lead screws is expected. In this paper, a balance of the load capacity of each screw flank was computed using the aerostatic guidance theory, so as to carry out a drunkenness analysis. It is found that the balancing effect plays the vital role in improvement on drunkenness of an aerostatic lead screw used in this study.

Gender differences have been identified in normal and traumatic motions of the spine. In the cervical region, spinal motions in females were significantly greater than in males during identical dynamic acceleration pulses [1]. Static cervical range of motion was also shown to be greater in female volunteers [2]. In the thoracic region, gender differences were identified in compressive and tensile elastic moduli [3]. Although male volunteers had slightly greater lumbar spine mobility, the difference was not statistically significant [4]. Another study reported that female lumbar specimens were somewhat more flexible than male specimens [5]. Lumbar spinal motions are clinically important in the diagnosis of abnormalities and instability. Increased motions occur secondary to instability and may indicate a need for spinal stabilization. However, although previous studies have provided baseline data for lumbar motions [6], possible variations in spinal motions between males and females may lead to inaccurate diagnosis. Therefore, the purpose of this investigation was to define lumbar spinal motions on a level-by-level basis to determine statistically significant differences between males and females and at varying levels of degeneration.

Gender Stereotyped design elements in gamification, such as using avatars aligned exclusively with the preferences of the male gender, may lead women not to develop their aptitudes or not perform adequately in male-prevalent groups, such as STEM fields (Science, Technology, Engineering, and Mathematics). This study aims to analyze the effects of stereotyped game elements in gamified tutoring systems on flow experience, self-efficacy, and learning performance. With this intent, we conducted an experimental study with Brazilian high school students. Findings indicated that stereotypes negatively affect the self-efficacy levels of female participants. Performance and flow experience levels were not affected by stereotypes. However, male participants were found to be more engaged (flow state) than women in the gamified tutoring system. These results suggest that educational technologies, such as tutoring systems and gamification, must have adaptable interfaces to avoid stereotyping and promote gender equity.

Abstract There are countless remarkable success stories of females in the oil and gas industry who have shattered glass ceilings and made significant contributions. These females have excelled in various roles, including engineering, geology, management, and leadership positions. Their achievements showcase their expertise, dedication, and resilience in a traditionally male-dominated industry. This paper aims to develop and enroll female youth to become an essential and integral part of the Oil & Gas operations. To achieve this, a mechanism has been established to enhance the Female leadership and decision-making skills. This involves creating a positive environment, developing a specialized tailored training program, ensuring active participation, and engagement. In addition, conducting competency assessments to identified gaps, while following up closely with their progress which will allow them to enhance their technical skills, performance and paving a robust career path for their progression. The expected results of this implementation will allow females to successfully handle responsibilities, manage and operate field activities without any limitation. Furthermore, implementing these programs and strategies will add value to the company, such as improved implementation of safety procedures, therefore increasing our productivity. Also, this will encourage all youth to lead the responsibility of a role in the sustainability and decarbonization, energy transition & future proving.

The decades-long low fertility of the population of Serbia is one of the biggest social challenges and a key component of population dynamics in the long term. Recent research suggests that the reduced progression to first and second child poses an increasingly significant challenge to the recovery of the total fertility rate despite the widespread perception that this is a reduction in higher child parity. At the same time, the pronounced gender imbalance in the spatial distribution of the population in their prime reproductive ages accelerates the processes of population aging and poverty in Serbia, despite the policy makers' goals presented through key national strategies regarding the country's sustainable development. Demographic analyses of changes in fertility patterns of the population in Serbia typically refer to females. Limiting the collection and interpretation of fertility data to women may lead to ignoring the specifics of men's reproductive behaviour, or to the assumption that the level, patterns, and changes in fertility do not differ significantly between men and women. The results of the 2022 Census in Serbia for the first time provide an opportunity to assess male fertility and perform a gender-sensitive analysis of fertility patterns. Existing research suggests that male fertility in Europe, especially in Eastern Europe, is lower than female fertility in recent periods, and that male fertility has declined faster than female fertility. Although the analysis of the results of the 2022 Census cannot conclude how this pattern has changed over time in Serbia, it will be very important to determine, from the aspect of pronounced differences in demographic capacities between areas and regions of Serbia that affect the demographic resilience of the country, what (dis)similarities exist between female and male fertility patterns, especially in their spatial distribution and settlement type. The aim of the paper is to identify patterns, correlations and trends in the fertility of the population of Serbia using statistical methods of longitudinal analysis of cohort fertility indicators of men and women - cumulative and specific according to age, birth order of the child, marital status, education and type of settlement based on the special processing of the 2022 Census data. The results will show whether current generations in reproductive age reach, exceed or fall behind the fertility level of previous generations. Also, by comparing these results with those of the 2011 Census, it will be possible to determine whether there have been changes in female fertility patterns in the intercensal period regarding relations between frequency of births, number of live births and mean age of women at birth of first child. The results of the analysis will contribute to a better understanding of the reproductive patterns of the population in Serbia, thus possibly helping in creation of more adequate policy measures in the field of family planning.

Impact loading of the lower legs can occur during a range of events such as car crashes, parachute landings, or anti-vehicular (AV) landmine blasts. This rapid, high-force loading can lead to debilitating injuries and long-term impairment. For military applications, the current lower leg injury standard is a maximum axial force of 5.4 kN, measured using a standard 50th percentile male Anthropomorphic Test Device (ATD) [1,2]. For an ATD leg to be an appropriate tool for assessing injury risk, it must have an impact response similar to that of the natural human leg.

Pulmonary artery hypertension (PAH) is a female dominant disease (the female-to-male ratio is 4:1), characterized by small distal pulmonary arterial narrowing and large proximal arterial stiffening, which increase right ventricle (RV) afterload and ultimately lead to RV failure [1,2]. Our recent studies have shown that collagen accumulation induced by chronic hypoxia increases the stiffness of the large extralobar pulmonary arteries (PAs) [3], and affects pulmonary vascular impedance (PVZ) [4]. The role of collagen in the female predominance in developing PAH has not been explored to date.

We explored the hypothesis that the Programme of Advancement through Health and Education (PATH), Jamaica's conditional cash transfer program, contributes to breaking the inter-generational poverty cycle by placing its urban beneficiaries on a higher educational trajectory. Using a regression discontinuity design, we found that PATH urban male beneficiaries who sat the Grade Six Achievement Test (GSAT) over the period 2010-2014 performed better on the test (scoring 16.03 points, or 3.6%, higher than non-beneficiaries); consequently, they were placed in better secondary schools (1.5 percentiles higher in a national school ranking based on placed students' GSAT scores). In contrast, we found no significant impact for urban girls.

Resumo:

This interdisciplinaray work combines expertise in engineering and entomology in Israel and the US, to develop an acoustic trap for mate-seeking female medflies. Medflies are among the world's most economically harmful pests, and monitoring and control efforts cost about $800 million each year in Israel and the US. Efficient traps are vitally important tools for medfly quarantine and pest management activities; they are needed for early detection, for predicting dispersal patterns and for estimating medfly abundance within infested regions. Early detection facilitates rapid response to invasions, in order to contain them. Prediction of dispersal patterns facilitates preemptive action, and estimates of the pests' abundance lead to quantification of medfly infestations and control efforts. Although olfactory attractants and traps exist for capturing male and mated female medflies, there are still no satisfactorily efficient means to attract and trap virgin and remating females (a significant and dangerous segment of the population). We proposed to explore the largely ignored mechanism of female attraction to male song that the flies use in courtship. The potential of such an approach is indicated by studies under this project. Our research involved the identification, isolation, and augmentation of the most attractive components of male medfly songs and the use of these components in the design and testing of traps incorporating acoustic lures. The project combined expertise in acoustic engineering and instrumentation, fruit fly behavior, and integrated pest management. The BARD support was provided for 1 year to enable proof-of-concept studies, aimed to determine: 1) whether mate-seeking female medflies are attracted to male songs; and 2) over what distance such attraction works. Male medfly calling song was recorded during courtship. Multiple acoustic components of male song were examined and tested for synergism with substrate vibrations produced by various surfaces, plates and loudspeakers, with natural and artificial sound playbacks. A speaker-funnel system was developed that focused the playback signal to reproduce as closely as possible the near-field spatial characteristics of the sounds produced by individual males. In initial studies, the system was tasted by observing the behavior of females while the speaker system played songs at various intensities. Through morning and early afternoon periods of peak sexual activity, virgin female medflies landed on a sheet of filter paper at the funnel outlet and stayed longer during broadcasting than during the silent part of the cycle. In later studies, females were captured on sticky paper at the funnel outlet. The mean capture rates were 67 and 44%, respectively, during sound emission and silent control periods. The findings confirmed that female trapping was improved if a male calling song was played. The second stage of the research focused on estimating the trapping range. Initial results indicated that the range possibly extended to 70 cm, but additional, verification tests remain to be conducted. Further studies are planned also to consider effects of combining acoustic and pheromonal cues.

Tilapias are among the most important aquaculture commodities worldwide. Commercial production of tilapia is based on monosex culture of males. Current methods for producing all-male fingerlings, including hormone treatments and genetic manipulations, are not entirely reliable, in part because of the genetic complexity of sex determination and sexual differentiation in tilapias. The goals of this project are to map QTL and identify genes regulating sex determination in commonly cultured tilapia species, in order to provide a rational basis for designing reliable genetic approaches for producing all-male fingerlings. The original objectives for this research were: 1) to identify the gene underlying the QTL on LG1 through positional cloning and gene expression analysis; 2) to fine map the QTL on LG 3 and 23; and 3) to characterize the patterns of dominance and epistasis among QTL alleles influencing sex determination. The brain aromatase gene Cyp19b, a possible candidate for the genetic or environmental SD, was mapped to LG7 using our F2 mapping population. This region has not been identified before as affecting SD in tilapias. The QTL affecting SD on LG 1 and 23 have been fine-mapped down to 1 and 4 cM, respectively, but the key regulators for SD have not been found yet. Nevertheless, a very strong association with gender was found on LG23 for marker UNH898. Allele 276 was found almost exclusively in males, and we hypothesized that this allele is a male-associated allele (MAA). Mating of males homozygous for MAA with normal females is underway for production of all-male populations. The first progeny reaching size allowing accurate sexing had 43 males and no females. During the course of the project it became apparent that in order to achieve those objectives there is a need to develop genomic infrastructures that were lacking. Efforts have been devoted to the development of genomic resources: a database consisting of nearly 117k ESTs representing 16 tissues from tilapia were obtained; a web tool based on the RepeatMasker software was designed to assist tilapia genomics; collaboration has been established with a sequencing company to sequence the tilapia genome; steps have been taken toward constructing a microarray to enable comparative analysis of the entire transcriptome that is required in order to detect genes that are differentially expressed between genders in early developmental stages. Genomic resources developed will be invaluable for studies of cichlid physiology, evolution and development, and will hopefully lead to identification of the key regulators of SD. Thus, they will have both scientific and agricultural implications in the coming years.

The lack of diversity in leadership positions within the Australian university sector has been a persistent issue, with predominantly older, white, male leaders holding power and shaping the future of higher education. While student demographics have become more diverse, the leadership of academic institutions has not kept pace with these changes. Therefore, as student expectations and attitudes change, university communities are encouraged to (re)consider their commitment to proactively addressing the structural inequalities that continue to impact the journeys of the students we seek to serve. Nevertheless, activist universities—those that proactively and visibly seek to lead on matters of socio-political importance—are few and far between. The referendum to change the constitution to recognise Aboriginal and Torres Strait Islander people through the establishment of a Voice to Parliament is an example where change has the potential to tangibly address educational inequality. The positions that institutions choose to take (or not), in relation to the attitudes held by a considerable proportion of our student cohorts, presents a strong argument for courageous leadership at all levels of our universities to lead, educate, and advocate for social good.

Background Most of Australian prawn aquaculture production is based on P. monodon. However, the Australian industry is under intense competition from lower priced overseas imports. The availability of all-female monosex populations, by virtue of their large size and associated premium prize, will offer competitive advantage to the industry which desperately needs to counteract competitors within this market. As for the redclaw production in Israel, although it is at its infancy, the growers realized that the production of males is extremely advantageous and that such management strategy will change the economic assumptions and performances of this aquaculture to attract many more growers. Original objectives (as in original proposal) Investigating the sex inheritance mechanism in the tiger prawn. Identification of genes expressed uniquely in the androgenic gland (AG) of prawns and crayfish. The above genes and/or their products will be used to localize the AG in the prawn and manipulate the AG activity in both species. Production of monosex populations through AG manipulation. In the prawn, production of all-female populations and in the crayfish, all-male populations. Achievements In the crayfish, the AG cDNA library was further screened and a third AG specific transcript, designated Cq-AG3, had been identified. Simultaneously the two AG specific genes, which were previously identified, were further characterized. Tissue specificity of one of those genes, termed Cq-AG2, was demonstrated by northern blot hybridization and RNA in-situ hybridization. Bioinformatics prediction, which suggested a 42 amino acid long signal anchor at the N-terminus of the deduced Cq-AG2, was confirmed by immunolocalization of a recombinant protein. Cq-IAG's functionality was demonstrated by dsRNA in-vivo injections to intersex crayfish. Cq-IAGsilencing induced dramatic sex-related alterations, including male feature feminization, reduced sperm production, extensive testicular apoptosis, induction of the vitellogeningene expression and accumulation of yolk proteins in the ovaries. In the prawn, the AG was identified and a cDNA library was created. The putative P. monodonAG hormone encoding gene (Pm-IAG) was identified, isolated and characterized for time of expression and histological localization. Implantation of the AG into prawn post larvae (PL) and juveniles resulted in phenotypic transformation which included the appearance of appendix masculina and enlarged petasma. The transformation however did not result in sex change or the creation of neo males thus the population genetics stage to be executed with Prof. Hulata did not materialized. Repeated AG implantation is currently being trialed. Major conclusions and Implications, both scientific and agricultural Cq-IAG's involvement in male sexual differentiation had been demonstrated and it is strongly suggested that this gene encodes an AG hormone in this crayfish. A thorough screening of the AG cDNA library shows Cq-IAG is the prominent transcript within the library. However, the identification of two additional transcripts hints that Cq-IAG is not the only gene mediating the AG effects. The successful gene silencing of Cq-IAG, if performed at earlier developmental stages, might accomplish full and functional sex reversal which will enable the production of all-male crayfish populations. Pm-IAG is likely to play a similar role in prawns.

Resumo:

We conduct a meta-analysis of 44 studies and 68 different managerial skills training programs, with the aim of identifying program characteristics that can lead to more effective public policies promoting firm growth and entrepreneurship. We synthesize 431 estimates to assess the effects of these programs on firm performance. Our findings show that, on average, managerial skills development programs have positive returns on management practices, firm productivity, profits, and survival. We also examine how program and participant specifications affect program effectiveness. Our analysis suggests that, on average, business training programs focused on human resources, soft skills, marketing, and finance-accounting, especially when organized by local organizations, tend to result in better firm performance. Moreover, training of potential entrepreneurs and managers in specifically targeted sectors such as agriculture, manufacturing, or services was more likely to result in improvement compared to non-targeted programs. Finally, our results indicate that programs that involve both male and female participants are more likely to enjoy higher effects from managerial training interventions.

Female and male mayors in Brazil responded differently to the COVID-19 crisis, with effects on mortality that varied over time. In the early months of the pandemic, female-led municipalities were less likely to close essential businesses and had higher COVID-19 death rates compared to male-led municipalities. Towards the end of the year 2020, however, female-led municipalities were more likely to close essential businesses and had fewer COVID-19 deaths than male-led municipalities. This suggests that female and male mayors handled the crisis in distinct ways, with implications for understanding gender differences in policymaking and crisis management.
