Women’s Autonomy in the Context of Rural Pakistan
The paper explores the elements that constitute women’s autonomy in rural Pakistan. Hitherto most research on women’s status in Pakistan has either been restricted to proxy measures of women’s status generally or to the urban areas. Community or region, each of which has distinctive features, have an overriding influence on this subject. Northern Punjabi women have lower economic autonomy but greater mobility and decision-making authority than women in Southern Punjab. Gender systems at the village level are also important predictors of women’s autonomy. Economic class has a weak and ambivalent influence on women’s autonomy in rural Punjab. Class influences both education and employment of women, these remains the routes to empowerment in rural settings. While most women in rural areas contribute economically, the majority works on the household farm or within the household economic unit. These women do not derive any additional autonomy as a result of this contribution. Paid employment, though offset by other restrictions on poor women, offers greater potential for women’s autonomy. Education, on the other hand, has a lesser influence on female autonomy in the rural Punjabi context.
Pakistani Couples: Different Productive and Reproductive Realities?
Gender systems depict several dimensions of the relations between men and women across different social settings. Mason (1995) has described the complexity of gender systems that encompass concepts such as women’s standing, empowerment, the sexual division of spheres and the rather widely used concept of women’s status. Gender systems in Pakistan are posited to be unequal in favour of men, because of strong patriarchal systems, which ordain that men and older persons make all major decisions. As a result, women’s status is argued to be low in most dimensions poor educational attainment, few economic opportunities apart from family based employment which is largely unpaid and the virtual seclusion of women from the public spheres of life especially those involving financial transactions. Spheres of life are quite separate with men having the primary responsibility of breadwinning and women to be primarily responsible for within household routine chores such as those involving cleaning, cooking, animal care and child care. Men control the major part of decision making and presumably act in their own interest which may not necessarily coincide with women [Folbre (1988)]. Especially in terms of productive decisions but also in reproductive decisions, women necessarily play a subsidiary role which relegates them to a lower position in terms of decision making and control of resources [Dwyer and Bruce (1988)]. This paper looks more closely at the two spheres of production and reproduction in rural Pakistan. It uses responses from matched husbands and wives to test whether in fact there is a difference between spouses in their perceptions, goals/orientation about production and reproduction.
Final Report of FORGE WP4.1.2: verification of critical stress theory applied to repository concepts
This report describes an experimental study of 48 separate experiments examining the validity of critical stress theory. Two main types of experiment were conducted: 1). Loading-unloading tests, where fracture flow was monitored at constant injection pressure as normal load was increased in steps to a given level and then reduced back to the starting stress state; 2). Gas breakthrough experiments, where gas injection pressure was increased in a pressure ramp at constant vertical load. These were conducted with and without active shear. It was found that critical stress theory is valid in predicting the preferential flow of gas in relation to the orientation of the fracture plane with respect to the maximum horizontal stress direction. However, loading unloading experiments showed that understanding the stress history of the rocks is of paramount importance and a mere knowledge of the current stress state is insufficient in accurately predicting the nature of fluid flow.
A total of 17 loading-unloading experiments were conducted, all on a 30° slip-plane. The main conclusions of this part of the study were; a). During a loading (vertical stress) and unloading cycle considerable hysteresis in flow was observed signifying the importance of stress history on fracture flow; b). For the case of gas injection the change in flow is chaotic at low normal loads, whereas for water injection the flow reduces smoothly with increased normal load; c). Hysteresis in horizontal stress observed during unloading demonstrates the importance of the ratio between horizontal stress and vertical stress and its control on flow; d). Differences have been observed between injection fluids (water and helium), especially the hysteresis observed in flow. For water injection flow is only partially recovered during unloading, whereas for gas enhanced flow is seen at low normal loads.
A total of 26 gas breakthrough experiments were conducted on 0°, 15°, 30°, and 45° discontinuities; both with and without active shear. All tests were conducted in an identical manner. The main conclusions of this part of the study were; a). During gas breakthrough experiments episodic flow/fault valve behaviour was seen with a decrease in subsequent peak pressures and the form of the pressure response was different during subsequent breakthrough events; b). Repeat gas injection testing had shown a consistent gas entry pressure but considerably different, non-repeatable, gas peak pressures; c). Differences in gas entry pressure were seen dependent on the orientation of the fracture; d). Shear can be seen to reduce the gas entry pressure, suggesting that shearing in kaolinite has the opposite effect of self-sealing to gas.
Other general observations of gas flow along fractures included; a). The flow of fluids through clay filled fractures is non-uniform and occurs via localised preferential pathways; b). The pressure recorded within the slip-plane showed a negligible fracture pressure and did not vary much in all tests
Bringing About a Behavioural Change in Providers to Meet the Reproductive Health Needs of Clients
The international conference on population and development held in Cairo in 1994 has became a historical turning point in the way population policies and programmes are perceived and sexual and reproductive health services are conceptualised and delivered. Inherent in the ICPD plan of action is the concept of care that recommends providing a range of reproductive health services to both men and women, that are safe and effective, and that satisfy clients, needs and wants. Clients are far more likely to use services that are of high quality. Achieving quality care requires complying with high technical and ethical standards (such as freedom of choice, informed consent, and freedom from coercion and abuse) and providing services at costs that are affordable to both clients and health care system. The most common barriers to quality are negative provider attitudes or behaviours, poor interactions between clients and providers, a lack of essential drugs and supplies in facilities, and delays in referrals to other necessary services. Pakistan has among the worst reproductive health indicators in the developing world. It has lagged behind many of its neighbours in terms of its social indicators. Access to health and educational facilities, especially in the rural areas has remained outstandingly weak. Maternal and infant mortality rates are unacceptably high at above 500 per 100,000 and 80 per 1000 births, respectively. Malnutrition, anaemia and reproductive tract infections are widely prevalent in women.
Summary Report of FORGE WP4.1.2: verification of critical stress theory applied to repository concepts
This report outlines the major conclusions from an experimental study of 48 separate experiments with the primary aim to verify critical stress theory.

Some Consequences of Rising Age at Marriage in Pakistan
Nuptiality changes have been at the core of demographic transitions in Europe and in several Asian societies [Caldwell (1993)]. Delayed marriages have been seen as precursors of fertility change in most societies. They underlie changes in family formation patterns and living arrangements, which ultimately are the bases of demographic transition. The concomitants of profound changes in marriage behaviour are worth studying because of their impact on demographic outcomes such as the population growth rate and fertility. Moreover, they are also strongly connected to the role and status of women, family living arrangements and power structures. The most prominent outcome of the rise in proportions single is that most young men and particularly young women begin experiencing profound changes in their lives. They essentially have several years of their lives "freed" from the responsibilities and changes associated with marriage, and in the case of girls from reproduction. The delay in marriage for females in particular has direct impact on delaying the age of sexual initiation and the age at first birth (since almost all childbearing occurs within marriage). But most importantly, it has direct influences on raising the potential for a larger amount of time between childhood and "adult" responsibilities allowing young people to develop their capabilities in terms of education and work.
Serum soluble transferrin receptor concentration as a biomarker of erythropoietic activity: surrogate marker of adequate transfusion in adult Beta-thalassaemia intermedia patients
Management of Beta (β)-thalassaemia intermedia in contrast to β-thalassaemia major patients has no clear guidelines as to indicators of adequate transfusion. Regular blood transfusion suppresses bone marrow erythropoietic activity. Serum soluble transferrin receptor (sTfR) concentration is a marker for erythropoietic activity, with increased sTfR being associated with functional iron deficiency and increased erythropoietic activity. This study aimed to determine the use of sTfR as an indicator of adequate transfusion in adult β-thalassaemia intermedia patients. A cross-sectional study was conducted at Hospital Ampang, Malaysia, for six months. Patient group included six β-thalassaemia intermedia and 34 HbE-β-thalassaemia transfused patients. None of the patients were on regular monthly blood transfusions as in β-thalassaemia major. The control group comprised of 16 healthy subjects with normal haematological parameters. Haemoglobin (Hb) analysis, sTfR and ferritin assays were performed. Hb and HbA percentages (%) were found to be significantly lower in patients compared to the controls, while HbE%, HbF%, sTfR and ferritin were significantly higher in patients. An inverse relationship was found in the controls between HbF% with Hb (r = -0.515, p < 0.05) and HbA% (r = -0.534, p < 0.05). In patients, sTfR showed an inverse relationship with HbA% (r = -0.618, p = 0.000) and a positive correlation with HbE% (r = 0.418, p = 0.007) and HbF% (r = 0.469, p = 0.002). Multivariate analysis showed that HbA% (r = 2.875, p = 0.048), HbE% (r = 2.872, p = 0.020) and HbF% (r = 2.436, p = 0.013) best predicted sTfR independently in patients. Thus, sTfR is a useful marker for erythropoiesis. The elevate sTfR in these patients indicate that the transfusion regimen used was inadequate to suppress ineffective erythropoiesis. Hb levels may not be the best target for monitoring transfusion treatment in β-thalassaemia intermedia patients, but the use of sTfR is helpful in individualising transfusion regimens
Education System Reform in Pakistan: Why, When, and How?
Pakistan's education system faces long-standing problems in access, quality, and equal opportunity at every level: primary and secondary schools, higher education and vocational education. In spite of recent encouraging trends, such as the rapid spread of private schooling and an expansion of higher education opportunities, systemic reform remains stubbornly elusive. The inability of successive governments to reform the system has created severe constraints for Pakistan's economic and societal development. An inability to act now will increase the problems manifold in the future, due to a burgeoning youth population and increasing competitive pressures from other developing countries that are devoting more attention to education. We discuss in this paper the imperative for education system reform in Pakistan, and articulate why a window of opportunity exists at this time for all stakeholders government, civil society and donors to initiate reform. We emphasize, however, some key messages. One, that reform must tackle all sectors of the education system primary/secondary, higher education and vocational education as Pakistan does not have the luxury to delay reform in one sector until the other sectors improve. Two, reform in every sector must be systemic i.e. with well-defined goals, focus on a minimal set of areas such as governance, financing, human resources, and curriculum and address them all together, rather than piecemeal. Three, implementation is the all-important Achilles' heel, where Pakistan has limited resources and has often foundered on the rocks. But as we discuss, there are important examples demonstrating that success is achievable, if government and civil society have the will to initiate and sustain reform
An experimental study of the flow of gas along synthetic faults of varying orientation to the stress field: implications for performance assessment of radioactive waste disposal
Critical stress theory states that fault transmissivity is strongly dependent upon orientation with respect to the stress tensor. This paper describes an experimental study aimed at verifying critical stress theory using a bespoke angled shear rig designed to examine the relationship between gas flows along a kaolinite-filled synthetic fault as a function of fault dip. A total of 22 gas injection experiments were conducted on faults oriented 0°, 15°, 30°, and 45° to horizontal; both with and without active shear. Gas flow was seen to be complex; repeat gas injection testing showed a consistent gas entry pressure but considerably different, nonrepeatable, gas peak or breakthrough pressure. Gas flow occurred along discrete, dilatant pathways. The physics governing the pressure at which these features formed was repeatable; however, permeability was dependent on the number, distribution, and geometry of the resultant pathways. The nonrepeatable gas response suggests that the number of pathways was dependent on very subtle variations in gouge properties. No fault orientations were seen to exhibit nonflow characteristics, although critical stress theory predicted that two of the investigated fault angles should be effective seals. However, a small variation in gas entry pressure was seen with fault angle as a result of varying normal and shear stress acting on the gouge material. Shear was seen to enhance gas movement by reducing gas entry pressure and increased permeability once gas became mobile. Therefore, in kaolinite gouge-filled faults, shear is not an effective self-sealing mechanism to gas flow
