Gaza disengagement revisited in light of October 7: Hidden multilateral dimensions of 2005 withdrawal revealed





The Hebrew University of Jerusalem




In the wake of the tragic events of October 7, 2023—when Hamas launched a deadly and unprecedented assault on southern Israel—scrutiny has intensified over the historical roots of Gaza’s political trajectory. Against this backdrop, a compelling new study by Professor Elie Podeh of the Hebrew University revisits Israel’s 2005 Gaza Disengagement Plan, challenging the widespread perception that the move was a strictly unilateral one.

In his article, titled “Israel’s 2005 Disengagement from Gaza: A Multilateral Move Under Unilateral Façade,” published in Middle Eastern Studies, Prof. Podeh reveals that the withdrawal—was the product of coordination between Israel, the Palestinian Authority, the United States, Egypt, Jordan, and the international Quartet.

Based on extensive archival research, including leaked diplomatic correspondence and firsthand interviews with Israeli and U.S. policymakers, the article demonstrates how key aspects of the disengagement were jointly developed. For instance, arrangements for border control, economic transition, and security cooperation were all negotiated behind the scenes, especially under the guidance of American envoys and Egyptian mediators. The involvement of James Wolfensohn, then special envoy of the Quartet, and the appointment of U.S. General William Ward to oversee security coordination, underscore the international stakes of the plan.

“The disengagement was presented as unilateral to serve Israeli domestic political aims and to minimize negotiations with a fragmented Palestinian leadership,” said Prof. Podeh. “Yet in reality, the move was a multilateral enterprise, shaped by regional and global stakeholders.”

The article also critiques the aftermath of the disengagement. Podeh attributes its failure to two parallel weaknesses: Israel’s decision not to use the withdrawal as a springboard for renewed peace negotiations, and the Palestinian Authority’s inability to assert effective control over Gaza, allowing Hamas and Islamic Jihad to fill the vacuum.

This dual failure, he argues, not only undermined the short-term viability of the disengagement but also planted the seeds of Gaza’s ongoing isolation and radicalization. Nearly two decades later, the implications of that strategy remain painfully relevant. The October 7 attacks shocked the region and underscored how the vacuum created by the disengagement has enabled Hamas’s dominance in Gaza—a dynamic that has endured, in part, due to the missteps of 2005.

 

Compassion makes employees more resilient when employers behave badly





North Carolina State University





New research finds that the more compassionate people are, the better able they are to deal with broken promises in the workplace. Specifically, the study suggests that compassion makes employees tougher: more emotionally resilient, higher performing, and less likely to seek new work when they feel their employer has broken a promise to them.

“People often equate compassion with weakness or softness, but this work underscores the ways in which compassion actually makes people resilient – and how that can affect their behavior in the workplace,” says Tom Zagenczyk, co-author of a paper on the work and a professor of management in North Carolina State University’s Poole College of Management.

At issue is a concept called psychological contract breach (PCB), which in this context refers to instances when an employee feels their employer has broken a promise. For example, the employee may not have gotten an expected raise or their employer’s mission may have changed in unexpected ways.

“There is already substantial research on what organizations and managers can do to maintain employee performance and reduce turnover when employees feel the employer hasn’t met agreed-upon obligations,” says Sara Krivacek, first author of the paper and an assistant professor of management at James Madison University.

“But there has been much less work done that focuses on the employees themselves,” Krivacek says. “We wanted to see how compassion may affect the way people cope with PCB in the workplace. Specifically, we wanted to look at two types of compassion: self-compassion, which is the extent to which people are kind and care for themselves; and other-compassion, the extent to which people are kind and caring toward other people.”

The researchers collected data for this study during the pandemic.

“This is significant because the lack of interaction with peers during the pandemic made it an opportune time to study the role an individual’s traits play in coping with PCB,” Zagenczyk says. “Typically, relationships with co-workers and supervisors help employees cope with PCBs on the job. Because people were working remotely, we were better able to determine the role that an individual’s personal characteristics play.”

For this study, the researchers conducted three surveys of English-speaking white-collar workers in the Netherlands at one-month intervals: 439 workers responded to the first survey; 382 of those workers completed the second survey; and 330 workers completed all three surveys.

The first survey was designed to determine the degree to which study participants experienced PCBs in the previous month. The second survey was designed to capture “violation feelings,” meaning negative feelings that employees had toward their employer – such as feelings of anger, betrayal or disappointment. The second survey also assessed each study participant’s levels of self-compassion and other-compassion. The third survey addressed issues such as intentions to leave the employer, job performance and emotional exhaustion.

“First off, the study tells us that violation feelings stemming from PCBs – anger, betrayal, etc. –are what drive negative outcomes like emotional exhaustion,” Krivacek says. “However, the study also tells us that compassion also plays a significant role in the extent to which people experience these negative outcomes – though the two types of compassion play very different roles.

“For example, we found that the higher an individual’s levels of self-compassion, the less emotionally exhausted they were – even when they were experiencing violation feelings after a PCB,” Krivacek says. “This suggests that self-compassion better equips individuals to deal with these negative emotions, which is important.”

“By the same token, employees with higher levels of other-compassion were less likely to consider leaving the job and reported higher levels of workplace performance,” Zagenczyk says. “This suggests that concerns about workplace colleagues make people less likely to slack off or quit, even when they feel their employer has acted badly.”

“In addition, while the results encourage employees to harness self- and other-compassion during challenging times at work, prior research suggests organizations can also foster this practice,” Krivacek says. “Specifically, self- and other-compassion are not just inherent traits; prior interventional work has shown that employees can develop and increase their own self- and other-compassion through training.

“Therefore, while organizations cannot realistically eliminate the degree to which employees experience PCB (that would be a broken promise in itself!), they can consider incorporating workshops and training programs that focus on fostering these practices,” Krivacek says. “Also, organizations prone to high levels of PCB may consider hiring job candidates with higher levels of compassion, if other factors such as knowledge, skills and abilities are relatively equivalent.”

The paper, “Softening the Blow: The Mitigating Effect of Compassion on the Negative Consequences of Psychological Contract Breach and Violation Feelings,” is published open access in the Journal of Business Ethics. The paper was co-authored by Yannick Griep, an associate professor at Samergo, Rotterdam, the Netherlands and North-West University, Potchefstroom, South Africa; and by Kevin Cruz, an assistant professor of management at Georgia Southern University.

 

Early-life low lead levels and academic achievement in childhood and adolescence




JAMA Network Open





About The Study:


 In this cohort study assessing early life low lead level and children’s and adolescents’ academic achievement, a 1-unit increase in lead levels in the range currently considered low for further interventions was associated with worse academic performance throughout school grades comparable to that for lead levels in the range recommended for additional interventions. These findings support the need to reconsider and potentially lower current blood lead reference values for recommending further interventions.

Coastal Alaska wolves exposed to high mercury concentrations from eating sea otters: research


UCalgary ecotoxicology expert Ben Barst contributes to study of marine food’s impact on predators



University of Calgary





In late 2020, a female coastal wolf collared for a study on predation patterns unexpectedly died in southeastern Alaska. 

The wolf, No. 202006, was only four years old. 

“We spent quite a bit of time trying to figure out the cause of her death by doing a necropsy and different analyses of tissues,” says Gretchen Roffler, a wildlife research biologist with the Alaska Department of Fish and Game.

“What finally came up was really unprecedented concentrations of mercury in this wolf’s liver and kidneys and other tissues.”

Roffler was put in touch with Dr. Ben Barst, PhD, an assistant professor in the Faculty of Science at the University of Calgary who was working at the University of Alaska Fairbanks at the time.

They, along with a team of other scientists, have now published new research in the journal Science of The Total Environment that shows wolves eating sea otters have much higher concentrations of mercury than those eating other prey such as deer and moose.

Mercury found in high concentrations in predators

Barst, an expert in ecotoxicology, says mercury is a naturally occurring element humans release from the Earth’s crust through coal combustion and small-scale gold mining.

“It’s a really weird metal in that it’s liquid at room temperature or it can be a vapour,” he says. “When it gets into the atmosphere in its elemental form, it can travel for really long distances.”

Barst says it also gets converted into methyl mercury when it gets into aquatic environments.

“It’s an organic form of mercury that really moves quite efficiently through the food web, and so it can reach high concentrations in predators that are tapped into aquatic food webs," he says. "So, we see higher concentrations in wolves that are tapped into a marine system.”

The latest research compares wolves from Pleasant Island — located in the Alaska Panhandle region, west of Juneau — with the population on the mainland adjacent to the island, as well as wolves from interior Alaska.

“The highest concentrations are the wolves from Pleasant Island,” says Barst, noting that the mainland population mostly feeds on moose and the odd sea otter.

He says there could be a number of factors driving the higher concentrations of mercury, but they are still researching several possibilities. 

Mercury-wolf health impact examined

Researchers are also doing more work to determine mercury’s role in impacting wolf health, as it remains unclear exactly what caused the death of Wolf No. 202006.

Barst notes, however, that years of data collected by Roffler show that 70 per cent of the island wolves’ diet is sea otters.

“They're eating so many sea otters that they're just getting this higher dose of mercury and it accumulates over time,” he says.

Roffler says there are other populations of wolves in Alaska as well as in B.C. that appear to be eating sea otters.

“It turns out that this might be a more widespread phenomenon than we thought originally,” she says. “At first I was surprised it was happening at all.”

It’s not yet known whether the sea otters off the B.C. coast also contain high levels of mercury.

Potential link to climate change

Back in Alaska, Barst says there’s a potential link to climate change due to the state's shrinking glaciers.

“We know that glaciers can release a tremendous amount of mercury,” he says. “In coastal Alaska, glaciers are retreating at some of the most rapid rates in the world.

“With that melting of glaciers, you get release of the particulate bedrock and some of that bedrock contains mercury – and so we don’t really know the fate of that mercury. It may just get buried in sediments or it may actually be available for conversion to methyl mercury and get into the food web.

“That’s part of what we’re doing now.”

 

Study finds Americans do not like mass incarceration

A new study, co-authored by an esteemed University of Cincinnati criminologist, has found that most Americans have an unfavorable opinion of mass incarceration.

The study — “Most Americans Do Not Like Mass Incarceration: Penal Sensibility in an Era of Declining Punitiveness” — was undertaken by criminologist Francis Cullen, a distinguished research professor emeritus in UC’s School of Criminal Justice, and a team of researchers from across the country to determine current perceptions about the American penal system.

Cullen says their findings are in line with other opinion polls that show a decline in “public punitiveness,”  or the tendency or desire to punish.

"There is a new 'penal sensibility’ known as a new way the public thinks about corrections in America,” Cullen says.

The researchers commissioned international online research data and analytics group YouGov to conduct a nationwide survey of 1,000 respondents.

The study, which now appears in the Journal of Experimental Criminology, found:  

  • Most Americans favor community programs for nonviolent and drug offenders as opposed to prison sentences.
  • Most do not want to spend tax dollars building more prisons; they favor spending money on prevention programs.
  • Few respondents have positive emotions about prisons.
  • Forty percent of Americans agree the prison system is racist.

These results, Cullen says, suggest that the “get tough” movement — starting in the 1970s — has lost traction in the United States. For half a century, he says, “America was in a punitive era in which prison populations grew rapidly, until reaching 2.3 million people incarcerated at times.” 

About 15 years ago, however, he says prison populations suddenly and unexpectedly stopped growing and then started to decline; Americans' punitiveness also started to decline, he says.

“Our paper probes whether these developments are signs of a correctional turning point in which a new penal sensibility has taken hold, when in fact it has,” says Cullen.

While the study shows Americans are not favorable toward mass incarceration, Cullen says that this does not mean that if someone commits a serious crime study respondents would not want the person locked up.   

“But it does mean that as a core policy, Americans do not want another era of mass incarceration,” says Cullen.

The research team included criminologists Alexander Burton, PhD, lead author from the University of Texas at Dallas; Cheryl Lero Jonson, PhD, from Xavier University in Cincinnati; and Justin Pickett from the University at Albany, State University of New York. Both Burton and Jonson earned their doctorates in criminology from UC’s School of Criminal Justice, under the tutelage of Cullen.

LAWRENCE — Researchers from the University of Kansas, with support from the KansasView and AmericaView programs, have created a web-based app for the public that provides free satellite monitoring and analysis of vegetation and crop health across Kansas and the nation, called the Sentinel GreenReport Plus.

The free digital tool integrates Google Earth Engine with high-resolution imagery from the European Space Agency’s Copernicus Sentinel-2 satellite mission, consisting of two identical satellites that share the same orbit. The Sentinel GreenReport Plus combines this satellite imagery with climate datasets from the PRISM group. As a public-service resource, the tool provides users with up-to-the-day insights into vegetation greenness, changes in land cover over time and climate abnormalities.

According to its KU creators, the Sentinel GreenReport Plus already has seen use in monitoring crops, assessing damage from drought, detecting changes in land use and tracking vegetation recovery following a disaster.

“Remote sensing and satellite imagery technology has been improving in terms of the spatial footprint that it can represent in a pixel,” said Dana Peterson, director of KansasView and senior research associate with Kansas Applied Remote Sensing, a program of the Kansas Biological Survey & Center for Ecological Research at KU. “This allows us to do more detailed monitoring of vegetation condition — it could be vegetation in a forest community, a cropland community or on rangeland. We could create a tool that would allow access to these data easily and create an interface where people — whether educators, researchers, ranchers or cropland producers — could access the imagery easily and look at vegetation health.”

The KU team said the public-facing digital tool could be used further to assess vegetation destruction from natural hazards or even more routine damage like hail. 

“We’ve also looked at some of the burn events and wildfires,” Peterson said. “You can look at how the vegetation has been damaged and to what extent and severity.”

The Sentinel GreenReport Plus improves detail and insight over the classic GreenReport, introduced in 1996 with support from NASA by the Kansas Applied Remote Sensing Program. The new Sentinel GreenReport Plus is underpinned by Copernicus Sentinel-2 satellite data, a much finer 10-meter resolution than the classic version relying on 1,000-meter resolution MODIS imagery.

Abinash Silwal, KU graduate student and tech lead in the project, said any agricultural producer could use the tools to assess the success of different crops, monitor crop health or compare crop conditions over time, which may indicate yield performance. The tool integrates USDA NASS Cropland Data Layers, which allows crop-specific stress analysis.

“We can look at vegetation health at the crop-type level,” Silwal said. “For example, if I want to monitor my field of corn, I can select ‘corn’ in the app and draw a rectangle or polygon around the area. The tool instantly displays multiple charts, including a time series and comparison charts showing current vegetation health relative to historical averages. This helps determine whether the crop's current condition falls within the normal range or is showing signs of stress.”

The heart of the Sentinel Green Report PLUS is underpinned by the Normalized Difference Vegetation Index. The Sentinel GreenReport PLUS has several key features:

  • Greenness Map: Uses the NDVI as a proxy for photosynthetically active plant biomass over a selected composite period.
  • Difference Map 1: Compares NDVI to the previous composite period within the same year, illustrating recent vegetation changes.
  • Difference Map 2: Compares NDVI to the same period from the previous year, highlighting year-over-year vegetation changes.
  • Difference Map 3: Compares current NDVI to the average NDVI from previous years, showing changes relative to historical trends.

 

Aside from Peterson and Silwal, the team that produced the Sentinel GreenReport Plus is composed of Chen Liang, former doctoral student; Jude Kastens, research associate professor and director of KARS; and Xingong Li, professor of geography & atmospheric science.

The KU researchers know stakeholders have found many features to be valuable. For instance, Silwal said the ability to compare vegetation health with precipitation adds a powerful dimension to understanding vegetation stress.

“The addition of the precipitation curve is the coolest thing,” he said. “If I see that vegetation health is below normal and the precipitation curve is flat or shows significantly lower rainfall compared to the 30-year historical statistics, we can infer that drought may be contributing to the stress. When the vegetation line is declining and the accumulated precipitation trend remains flat or below average, it points to possible drought conditions affecting crop health.”

These breakthroughs should lead to better-informed agricultural producers, policymakers, insurers and research ecologists in Kansas and across the nation, Peterson said.

She added the Sentinel GreenReport Plus might represent “a better way to understand the interplay of climate and vegetation. Users can visualize trends, generate crop-specific charts and download outputs to support reports, presentations and further analysis.”
